MC3302PG - 4-Channel 3-36V Comparator | onsemi
N.º de pieza: MC3302PG ✓ ActivoMC3302PG Descripción general
A comparator is an analog integrated circuit that compares two input voltages and produces a logic-level indication of their relationship. The MC3302PG belongs to the comparator hierarchy within analog ICs and interface ICs. Its four independent channels allow a single package to perform multiple threshold, level-detection, low-level-sensing, or memory-interface functions while operating from one supply rail.
The primary electrical features are the wide 3 V to 36 V operating range, four general-purpose comparator channels, 1.3 microsecond response time, and 1 mA supply current. CMOS and TTL output compatibility allows the open-collector outputs to interface with a broad range of digital logic. The 14-pin PDIP package also supports conventional through-hole assembly and hand prototyping without requiring a fine-pitch surface-mount footprint.
Each comparator section is intended to operate from the same single supply, making the IC suitable for systems where a positive supply rail is available but split bipolar rails are not. Open-collector outputs provide a flexible output architecture, while the common-device package simplifies inventory and reduces the number of discrete comparator components required on a board. The 1.3 microsecond response time is appropriate for threshold monitoring and control functions that do not require sub-microsecond timing.
Typical uses include level detection, low-level sensing, memory applications, industrial control inputs, consumer equipment, automotive signal interfaces, and digital threshold crossings. The four-channel arrangement is particularly useful when several sensed voltages must be compared against independent references or when redundant comparator decisions are needed within one package.
Designers should account for the open-collector output configuration, including pull-up requirements and pull-up resistor selection. Input common-mode range, output saturation behavior, supply-current variation, and input offset must be checked against the manufacturer datasheet for the exact operating condition. Input leads should be routed away from switching nodes and noisy return paths to prevent false comparator transitions.

Aplicaciones típicas
MC3302PG es adecuado para 6 aplicacións: Industrial Level Detection, Automotive Signal Interface, Memory Interface and Control, Consumer Equipment Threshold Monitoring, Low-Level Sensing, Power-Supply Supervision.
Industrial Level Detection
The MC3302PG fits industrial level-detection systems because four independent general-purpose comparator channels can evaluate multiple sensed voltages within one 14-PDIP package. Its 3 V to 36 V supply range supports a single positive rail across widely separated industrial voltage levels, and the 1.3 us response time is suitable for routine threshold events. Each open-collector output can drive CMOS or TTL-compatible logic when paired with a suitable pull-up. Place each sensor near its comparison network when possible, keep high-current switching paths separated from the input traces, and confirm that every sensor voltage remains within the comparator input common-mode range. The four-channel arrangement reduces component count and simplifies maintenance compared with four discrete comparator packages.

Automotive Signal Interface
The MC3302PG can be used to translate automotive or industrial signal levels into logic-compatible decisions when the interface operates from a single positive supply. Its 3 V to 36 V operating range provides broad supply flexibility, while the four channels allow simultaneous monitoring of several inputs. The 1.3 us response time is appropriate for switches, relays, and supervisory signals that do not require sub-microsecond response. Because the outputs are open collector, the design must include pull-up resistors sized for the target logic family and the aggregate pull-up current must be included in the supply budget. Automotive qualification status and the complete operating-temperature range must be confirmed in the manufacturer documentation before use in a safety- or reliability-critical vehicle system.
Recomendado
Memory Interface and Control
The MC3302PG is designed for memory-interface and threshold-control applications, making its four comparator channels useful for comparing sensed signals against reference levels. A 1.3 us response time provides useful margin for ordinary memory-control events, while the single 3 V to 36 V supply architecture simplifies systems that do not provide split positive and negative rails. Use the open-collector outputs with pull-up resistors selected for the associated CMOS or TTL input. To avoid data corruption, place the comparator inputs away from high-energy switching nodes, use a stable reference source for threshold generation, and account for input offset and noise during worst-case timing analysis. The 14-PDIP format also supports straightforward through-hole assembly and bench-level hardware verification.
Recomendado
Consumer Equipment Threshold Monitoring
The MC3302PG is appropriate for consumer equipment that monitors several analog conditions and reports logic decisions to a controller. Four channels in one 14-PDIP package reduce board area and component count, while the 1.3 us response time is suitable for button, sensor, and power-state detection. The device operates from a single 3 V to 36 V supply, although the selected system rail must still satisfy the input and output requirements of every compared signal. Add pull-up resistors to each open-collector output and select values that balance rise time against current consumption. A common ground plane and short input routes help prevent switching disturbances from producing false threshold transitions, particularly when a sensor or switching regulator shares the same board.
Recomendado
Low-Level Sensing
The MC3302PG's general-purpose comparator architecture and 1.3 us response time make it suitable for detecting low-level sensor outputs in consumer, industrial, and automotive electronics. Four channels permit independent monitoring of different low-voltage conditions while sharing one single-supply rail from 3 V to 36 V. The sensing accuracy will depend on the reference source, input offset, noise, and the relationship between the sensed voltage and the allowable common-mode range, so these items must be reviewed in the manufacturer electrical tables. Use open-collector outputs with pull-up resistors matched to CMOS or TTL logic requirements. Keeping comparator inputs short and separated from relay coils, inductive chokes, and switching-node currents helps prevent false transitions near the decision threshold.
Recomendado
Power-Supply Supervision
The MC3302PG can supervise multiple power-related thresholds when a system uses a positive supply rail between 3 V and 36 V. Its four channels can independently monitor input, auxiliary rails, battery transitions, or divided feedback voltages, and the 1.3 us response time is suitable for conventional supervisory events. The open-collector outputs permit wired logic-level signaling with pull-up resistors and can be connected to a controller or system-reset logic. Design the divider values so that every monitored voltage remains inside the comparator input common-mode range, and include tolerance and offset in the threshold budget. The 14-PDIP package simplifies through-hole prototypes, while its four channels reduce the footprint required for multiple supervision functions.

Notas de diseño
Do not treat an open-collector output as a actively driven logic output. Fit a pull-up resistor to each output used as a logic signal, verify that its high level meets the receiving CMOS or TTL input requirement, and include the resulting current in the supply budget. If multiple outputs share one pull-up node, their combined pull-up current must remain within both the output-device and logic-device limits.
Route the two inputs of each comparator as a short, adjacent pair and keep them away from relay-coil wiring, switching inductors, and high-current power paths. Connect the comparator ground to the quiet analog or logic ground reference at the device rather than routing it through a noisy power return. Short input traces reduce susceptibility to induced spikes that could cause an incorrect threshold transition.
Budget the comparator supply using the 1 mA listed device specification plus the current drawn by each output pull-up network. The MC3302PG supports a 3 V to 36 V operating range, but every input and output signal must also remain within its electrical limits. Use local bypass capacitance near the supply pins and maintain a common, low-impedance return path to reduce supply disturbances during output transitions.
When the comparator is used near a decision threshold, include input offset, noise, and reference tolerances in the timing and accuracy calculation rather than relying only on the 1.3 us nominal response time. A stable reference and deliberate input filtering are generally preferable to adding delay to compensate for an unstable threshold. Verify the complete design across supply-voltage and temperature corners using the manufacturer limits.
