TS374ID Low-Power Quad Comparator | STMicroelectronics
MPN: TS374ID ✓ সক্রিয়TS374ID সারাংশ
A voltage comparator is an analog signal-conditioning integrated circuit that compares two input voltages and changes its output state when the difference crosses a defined threshold. The TS374ID belongs to the comparator hierarchy, within analog ICs and signal-conditioning semiconductors. Its four channels can perform independent comparisons while sharing one supply and ground connection, reducing component count in multi-channel monitoring designs.
Key characteristics include four independent differential comparators, low-power CMOS operation, low input offset voltage, a 3 V to 16 V operating range, and open-drain outputs. The open-drain architecture allows each output to be pulled up to the required logic level with an external resistor, which is useful when interfacing the TS374ID to systems operating above or below its supply voltage.
The TS374ID uses STMicroelectronics silicon linear MOS technology to achieve its consumption-to-speed balance. Its typical 200 ns response time supports faster threshold decisions than general-purpose slow comparators, while the high typical input impedance reduces loading on the sensed source. Each differential input pair provides a non-inverting and an inverting comparison input, and the output indicates which input is higher.
Typical uses include sensor threshold detection, battery and power-supply monitoring, industrial control logic, window comparators, overvoltage detection, and general digital control interfaces. The quad configuration is particularly useful when a board must monitor several independent analog quantities, such as temperature, pressure, current, or supply rails.
Designers should use pull-up resistors on all open-drain outputs and confirm that output rise time, input common-mode range, and supply timing meet the system requirements. Care is also needed when several comparators can pull an output low simultaneously, because the shared pull-up resistor must tolerate the combined sink current.
This page combines the TS374ID electrical characteristics, package details, practical circuit considerations, and package-compatible replacement guidance to support faster component selection, footprint verification, and second-source planning.

TS374ID এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Industrial Sensor Threshold Detection, Battery and Power-Supply Monitoring, Overvoltage and Undervoltage Protection, Window Comparison and Limit Control, Digital Control Interface, Portable and Battery-Powered Equipment.
Industrial Sensor Threshold Detection
The TS374ID fits industrial sensor threshold detection because its four independent differential channels can compare multiple sensor outputs without requiring four separate comparator packages. The 3 V to 16 V operating range supports common industrial supply levels, while the typical input impedance of 10^12 ohm minimizes loading on high-impedance sensor networks. A 200 ns typical response permits quick decisions around process limits or alarm setpoints. Each channel should use its differential inputs around the required threshold and its open-drain output should have a pull-up resistor to the controlling logic voltage. Verify the input common-mode range and account for the maximum operating temperature of 125 °C.

Battery and Power-Supply Monitoring
The TS374ID is useful for monitoring several battery or power-supply conditions in one compact circuit. Four differential channels can supervise individual rails, charger status signals, or divided battery voltages, while the 3 V to 16 V supply range provides flexibility across low- and mid-voltage systems. Open-drain outputs can pull down a shared fault or power-enable line, although the pull-up resistor must be sized for the combined sink current when multiple channels activate together. The low-power CMOS design also avoids the higher quiescent demand associated with many bipolar comparators. Confirm each monitored voltage remains inside the input common-mode range before selecting resistor dividers.

Overvoltage and Undervoltage Protection
The TS374ID supports independent overvoltage and undervoltage protection by dedicating its four differential comparator channels to separate power conditions. A resistor-divider network can translate each monitored rail to the comparator input range, and the open-drain output can directly drive a system fault line or regulator disable function. Its 200 ns typical response time supports fast fault detection, but propagation through external dividers and pull-up networks should also be included in the end-to-end response assessment. The 3 V to 16 V operating range allows the comparator to be powered from a regulated rail in many systems. Validate common-mode limits, output sink current, and behavior during startup.

Window Comparison and Limit Control
The TS374ID is appropriate for window comparison because each differential channel can evaluate whether an input lies above, below, or between selected limits. Four channels can monitor one analog quantity at several thresholds or compare multiple quantities against lower and upper limits. Open-drain outputs make it possible to combine channel states into a wired fault indication when the circuit design permits wired-AND operation. The high typical input impedance of 10^12 ohm reduces the effect of threshold dividers, and the 200 ns typical response provides rapid switching for control decisions. Size the pull-up network for the required rise time and worst-case number of simultaneously low outputs, while confirming the input common-mode range.

Digital Control Interface
The TS374ID can serve as the analog decision-making front end for a digital controller. External sensor signals or resistor-divider outputs enter the differential inputs, and the open-drain comparator outputs translate analog threshold crossings into logic states for a microcontroller, programmable controller, or monitoring circuit. The quad arrangement consolidates several decisions into one 14-pin SOIC package, helping conserve PCB area. Its low-power CMOS operation and typical 200 ns response are useful when the controller must react quickly without continuously switching a large converter. The external pull-up voltage can match the controller logic level, but the resulting rise time and the comparator input common-mode limits must be checked before layout release.

Portable and Battery-Powered Equipment
The TS374ID supports compact battery-powered equipment that requires several low-power threshold decisions. Its low-power quad CMOS implementation provides four comparison channels in a single 14-pin SOIC package, while the 3 V to 16 V supply range covers common portable-system rails. The high typical input impedance helps preserve battery life when the comparator monitors high-impedance dividers or sensing nodes. Open-drain outputs permit pull-ups to a nearby low-voltage logic rail and can limit current by using appropriately sized resistors. Design the system so inactive channels do not prevent the required supply current from being reached, and verify the complete signal range against the input common-mode specifications.

ডিজাইন নোট
Route each differential input as a short, impedance-matched pair and keep it away from high-current switching nodes. Place the external pull-up resistor close to the associated open-drain output so that parasitic capacitance does not excessively slow the rising edge. Preserve a continuous ground-return path beneath the device where the board layout permits, and check the manufacturer pin-description table before assigning all 14 package pins.
Calculate the output rise time from the pull-up resistance, load capacitance, and the comparator’s sink-current limit rather than relying only on the 200 ns typical response specification. If several open-drain outputs share one pull-up, verify the maximum combined sink current and the resulting logic-low level. Add filtering only where required, because excessive capacitance can slow transitions and change the effective system response.
Confirm that every input voltage remains inside the comparator’s common-mode range at the minimum operating supply. Do not assume that the 3 V to 16 V supply rating automatically permits input signals spanning the full supply rail. Also distinguish the device’s maximum operating temperature from the temperature grades of replacement variants, since an otherwise pin-compatible part may not satisfy high-temperature requirements.
Use a local bypass capacitor at the supply pins and keep the return connection short to reduce supply noise coupled into the threshold decision. Because the outputs are open-drain, the pull-up voltage may differ from the comparator supply, but it must remain within the output and downstream-device limits. Verify startup behavior so that an uncontrolled input does not create an unintended fault indication or power-enable transition.
