Nexperia USA Inc. 74HCT1G00GW,165

Overview

74HCT1G00GW,165 from Nexperia is a single 2-input NAND gate in TSSOP5 (SOT353-1) package, designed for level translation between TTL and CMOS logic domains. It operates from 4.5 V to 5.5 V, delivers symmetrical output impedance (±2.0 mA drive), supports -40 °C to +125 °C ambient operation, and features TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V). It is used in digital control signal conditioning for industrial I/O modules.

For engineers reviewing the 74HCT1G00GW,165 datasheet, 74HCT1G00GW,165 pinout, 74HCT1G00GW,165 application, or 74HCT1G00GW,165 equivalent, key selection criteria include input voltage compatibility with legacy TTL systems, propagation delay stability across temperature (tpd = 12–27 ns at CL = 50 pF), low ICC supply current (<20 μA at VCC = 5.5 V), and robust ESD protection (HBM >2000 V, CDM >1000 V).

Technical Context

This device implements a standard two-input NAND Boolean function with fully buffered inputs and outputs. Its TTL-level input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 5.0 V) enable direct interfacing with 5 V TTL logic families without external level shifters. Input clamp diodes allow safe operation with input voltages exceeding VCC when used with current-limiting resistors.

The output stage provides symmetrical sourcing and sinking capability (IOH/IOZ = ±2.0 mA at VCC = 4.5 V), ensuring consistent rise/fall times and noise immunity. Propagation delays are balanced (tPLH ≈ tPHL), and static characteristics are specified over full industrial and extended automotive temperature ranges (-40 °C to +125 °C).

FAQ

What is the maximum operating frequency supported by the 74HCT1G00GW,165?

The device does not specify a maximum clock frequency, as it is a combinational logic gate. Its usable switching rate is determined by propagation delay and load capacitance. With CL = 50 pF and VCC = 4.5 V, tpd(max) = 27 ns, supporting reliable operation up to approximately 18 MHz in feedback-free configurations. For synchronous systems, ensure setup/hold margins exceed tpd variation across voltage and temperature.

Can the 74HCT1G00GW,165 operate at 3.3 V supply?

No - the 74HCT1G00GW,165 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V) remain valid, but VOH and VOL degrade beyond specification limits, and propagation delay increases significantly. Use 74LVC1G00 for 3.3 V systems or add a level translator if interfacing with 3.3 V sources.

Is the 74HCT1G00GW,165 pin-compatible with the 74HC1G00GW,165?

Yes - both share identical TSSOP5 (SOT353-1) pinout and footprint. However, the 74HC1G00GW has CMOS input thresholds (VIH = 70% VCC), making it unsuitable for direct TTL input interfacing. Swapping requires verification that driving sources meet HC-level thresholds and that system timing budgets accommodate longer tpd at lower VCC.

Does the 74HCT1G00GW,165 require external pull-up or pull-down resistors on inputs?

No - inputs are internally clamped and have negligible leakage (<1.0 μA), so they do not float. Pull resistors are only needed if the driving source is high-impedance (e.g., open-collector) or if a defined default state is required during power-up/reset. In standard push-pull TTL or CMOS driver configurations, no external biasing is necessary.
