TS374CN - Quad CMOS Comparator, 3-16 V, 14-DIP | STMicroelectronics
MPN: TS374CN ✓ সক্রিয়TS374CN সারাংশ
A voltage comparator is an analog integrated circuit that compares two input voltages and produces a digital logic result indicating which input is higher. Comparators belong to the broader interface IC and signal-conditioning hierarchy, where they convert continuously varying analog signals into logic-compatible decisions. The TS374CN's four independent channels make it useful wherever several threshold or sorting decisions must be performed by one device.
The TS374CN provides four low-power precision comparators using a LinCMOS process. Its open-drain outputs allow the output node to be pulled up to a compatible supply through an external resistor, which supports wired-AND or wired-OR behavior when several outputs share a node. Typical input offset voltage is low, while the approximately 10^12-ohm typical input impedance minimizes loading on high-impedance sensor and divider networks.
Operation from 3 V to 16 V makes the device suitable for 5 V logic systems and higher-voltage industrial interfaces. Maximum quiescent current is listed as 250 uA, reducing the impact of continuous comparator operation. The open-drain architecture can also support level translation when the pull-up supply differs from the comparator supply, provided voltage and timing limits are respected.
Typical uses include sensor threshold detection, battery and power-supply monitoring, window comparators, overvoltage and undervoltage protection, signal crossing detection, and four-channel digital conditioning. The 200 ns typical response is suitable for many control and monitoring loops, although propagation-delay variation, input overdrive, and output pull-up resistance must be checked in fast systems.
The principal design consideration is the open-drain output. Every used output requires an external pull-up resistor, and the resistor must satisfy the sink-current and rise-time requirements of the connected logic. Inputs should remain within the common-mode range, and unused comparator channels should be tied to defined logic levels rather than left floating.

সাধারণ ব্যবহার
TS374CN এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Sensor Threshold Detection, Power Supply Monitoring, Battery Voltage Protection, Window Comparator Control, Digital Signal Conditioning, Overvoltage and Undervoltage Protection.
Sensor Threshold Detection
The TS374CN is well suited to comparing a sensor-derived voltage with a reference because its typical input impedance is 10^12 ohms and input bias current is only 1 pA at 5 V, minimizing loading of high-impedance divider networks. Each of the four channels can independently detect whether a signal has crossed a defined threshold. A typical implementation places the sensor signal on one input and a resistor-divider reference on the other, then uses feedback around the comparator when hysteresis is required. The 200 ns typical response supports many monitoring loops, while the 3 V to 16 V supply range covers both 5 V logic and higher-voltage industrial interfaces.

Power Supply Monitoring
TS374CN channels can monitor multiple power rails by comparing divided supply voltages against stable references and driving fault indicators, load switches, or system logic. The 3 V to 16 V operating range is useful for 5 V, 12 V, and 15 V systems, and maximum quiescent current of 250 uA limits the continuous overhead of always-on protection. Because the outputs are open-drain, each channel can pull a shared wired-AND fault line low, while an external pull-up establishes the high logic level. Design the dividers to remain below the input common-mode limits and account for output rise time when the fault signal must respond rapidly.

Battery Voltage Protection
The TS374CN can act as a discrete battery-protection element by comparing a scaled battery voltage against a reference to detect overvoltage, undervoltage, or an invalid operating range. Its low typical input bias current of 1 pA at 5 V reduces errors caused by high-value divider resistors, helping preserve battery life and measurement accuracy. The 250 uA maximum quiescent current is particularly relevant in portable equipment. An open-drain fault output can directly pull a protection latch, charger inhibit, or load-disconnect signal low, although the external pull-up must be selected for the actual logic rail and output leakage conditions.

Window Comparator Control
TS374CN is appropriate for upper- and lower-bound window detection where two comparators establish the permitted operating range of a signal. The fourth channel can perform an independent auxiliary comparison, such as a fault heartbeat or interlock. Its open-drain outputs simplify combining upper-limit and lower-limit events into a common wired fault indication. For stable operation, select reference voltages away from the signal's transition region, add controlled hysteresis, and verify that the 200 ns typical response remains acceptable with the selected pull-up resistance, board capacitance, and system input filtering.

Digital Signal Conditioning
The TS374CN converts a slowly varying analog signal into a logic state when the signal crosses an adjustable reference. Its approximately 10^12-ohm typical input impedance is useful when the signal originates from a high-impedance divider, sensor, or test fixture, while low input bias current helps limit source loading. The open-drain output can drive a pull-up rail or participate in a wired logic network. Keep the compared signal within the input common-mode range, add filtering where noise could cause repeated transitions, and treat the 200 ns value as typical rather than a guaranteed maximum propagation delay.

Overvoltage and Undervoltage Protection
TS374CN supports independent overvoltage and undervoltage detection in industrial control, instrumentation, and embedded systems. Resistor dividers scale the monitored rail into the comparator input range, while a reference determines the trip point. The open-drain output can directly drive an active-low fault input on a controller, isolation interface, or relay driver. The device's 3 V to 16 V operating range covers common control voltages, and its 250 uA maximum quiescent current keeps supervisory overhead modest. Verify common-mode limits, input offset, pull-up current, and the effect of divider tolerance over the full operating temperature range.

ডিজাইন নোট
Every used open-drain output requires an external pull-up resistor. Select the resistor using the required logic rise time, total output capacitance, input leakage, and maximum sink current. Excessive resistance increases rise time and susceptibility to noise; excessive resistance can also prevent the output from discharging a logic input within the system timing budget.
Keep comparator inputs away from switching nodes and route them over a continuous ground plane. Place the input divider or sensor source close to the device when possible, minimize loop area, and use a local bypass capacitor close to the supply pin. If a slow signal crosses the threshold repeatedly, add positive feedback for hysteresis or apply a small input filter rather than relying on software to suppress the transitions.
The maximum listed quiescent current is 250 uA, but total supply demand also includes comparator input currents and output pull-up current. In battery-powered systems, calculate the pull-up load continuously because an open-drain output held high by a resistor can consume more average power than the comparator itself. Use the highest suitable pull-up voltage only when the connected device and TS374CN output ratings permit it.
কমপ্লায়েন্স তথ্য
RoHS, REACH, lead-free, halogen-free, and conflict-minerals declarations were not identified in the source material. AEC-Q100 is not applicable because TS374CN is a commercial-temperature comparator rather than an automotive-qualified device.
