Nexperia USA Inc. 74HC1G32GW,165

Overview

74HC1G32GW,165 from Nexperia is a single 2-input OR gate logic IC in TSSOP5 (SOT353-1) package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, propagation delay as low as 7 ns at 6.0 V/50 pF, and guaranteed operation from −40 °C to +125 °C - used for discrete logic combining, enable signal generation, and bus arbitration in industrial control and sensor interface circuits.

For engineers reviewing the 74HC1G32GW,165 datasheet, 74HC1G32GW,165 pinout, 74HC1G32GW,165 application, or 74HC1G32GW,165 equivalent, this page delivers verified pin functions, real-world timing behavior under load, thermal derating data for TSSOP5, input clamping diode implementation details, and direct substitution guidance against industry-standard alternatives.

Technical Context

The 74HC1G32GW,165 implements a single 2-input positive-logic OR function using standard CMOS silicon technology, with symmetrical output drive capability (±12.5 mA) and balanced tPLH/tPHL propagation delays. Its input structure includes integrated clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used.

It operates across two logic families: HC (CMOS-compatible inputs) and HCT (TTL-compatible inputs), though this specific part number denotes the HC variant. Static parameters include VIH = 4.2 V min at VCC = 6.0 V and VOL = 0.33 V max at IO = 2.6 mA, ensuring robust noise margins in mixed-voltage systems.

FAQ

Can 74HC1G32GW,165 operate reliably at 2.0 V supply?

Yes - it is fully specified down to 2.0 V with VIH = 1.5 V min and VOL = 0.1 V max at IO = 20 μA, enabling use in battery-powered 2.5 V systems. Propagation delay increases to 115 ns at 2.0 V/50 pF, which remains acceptable for control logic where speed is secondary to ultra-low power.

Does this device require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied HIGH or LOW externally, but not left floating. The datasheet explicitly prohibits floating inputs due to increased ICC and potential oscillation. Internal clamp diodes do not eliminate this requirement; they only protect against overvoltage, not undefined logic states.

What is the maximum capacitive load this OR gate can drive without signal degradation?

It is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤ 23 ns at VCC = 4.5 V). Driving >50 pF increases propagation delay nonlinearly and may cause overshoot/ringing; for >100 pF loads, add a series resistor (22–47 Ω) near the output to dampen reflections and maintain signal integrity.

Is the TSSOP5 package (SOT353-1) compatible with standard reflow profiles?

Yes - the SOT353-1 package is rated for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C for 30 seconds. Its 1.25 mm body width and 0.65 mm pitch are supported by mainstream SMT assembly lines; no special stencil or placement adjustments are required beyond standard 0.4 mm aperture reduction for fine-pitch.
