Nexperia USA Inc. 74HCT00PW-Q100,118

Overview

74HCT00PW-Q100 from Nexperia is an automotive-qualified quad 2-input NAND gate in TSSOP14 package, operating from -40 °C to +125 °C with 4.5–5.5 V supply, TTL-compatible inputs, and guaranteed 24 ns max propagation delay at VCC = 4.5 V. It delivers high noise immunity, latch-up immunity >100 mA, and ESD protection (HBM >2000 V, CDM >1000 V), used in automotive body control modules for logic-level signal conditioning and discrete gate-based control sequencing.

For engineers reviewing the 74HCT00PW-Q100 datasheet, 74HCT00PW-Q100 pinout, 74HCT00PW-Q100 application, or 74HCT00PW-Q100 equivalent, key selection criteria include TTL-level input compatibility, AEC-Q100 Grade 1 qualification, TSSOP14 thermal performance, and verified 24 ns propagation delay under automotive temperature extremes.

Technical Context

This device implements four independent 2-input NAND gates using silicon-gate CMOS technology with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL logic without level shifters. Input clamp diodes allow safe operation with input voltages exceeding VCC when current-limited.

It operates across a fixed 4.5–5.5 V supply range with static output drive capability of ±4.0 mA, low ICC (≤40 μA at VCC = 6.0 V), and dynamic power dissipation governed by CPD = 22 pF - critical for low-power automotive subsystems where standby current and switching loss must be tightly controlled.

Key Specifications

Pinout & Package

TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14-lead, 4.4 mm body width, 0.65 mm pitch, exposed pad not electrically connected - optimized for automated optical inspection (AOI) and thermal performance in dense automotive PCB layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad NAND gate applications.

Compared with 74HCT00PW-Q100, the D variant trades thermal efficiency for mechanical serviceability, while the BQ variant improves thermal density and footprint but requires fine-pitch reflow process control - making PW the balanced choice for mainstream automotive control units.

FAQ

Is 74HCT00PW-Q100 pin-compatible with non-automotive 74HCT00 variants?

Yes - it shares identical pinout (TSSOP14, SOT402-1) and logic function with standard 74HCT00PW, but differs in qualification: only the -Q100 suffix denotes AEC-Q100 Grade 1 testing, extended temperature validation (–40 °C to +125 °C), and automotive-specific reliability screening including HTSL and biased HAST.

Can 74HCT00PW-Q100 operate at 3.3 V supply?

No - its recommended operating range is strictly 4.5 V to 5.5 V. At 3.3 V, VIH/VIL thresholds fall outside specification (VIH min = 2.0 V requires ≥4.5 V for margin), and output drive degrades below guaranteed levels; use 74LVC00 or 74AHC00 for 3.3 V systems.

What is the purpose of the exposed thermal pad in the TSSOP14 package?

The exposed pad in SOT402-1 is non-functional and unconnected - Nexperia specifies no electrical or mechanical requirement to solder it. If soldered, it must remain floating or tied to GND; it does not improve thermal performance significantly versus standard TSSOP thermal path.

How does input clamping affect interfacing with 12 V automotive sensors?

Clamp diodes allow safe connection of 12 V signals to inputs when paired with ≥10 kΩ series current-limiting resistors - limiting IIK to <±20 mA per pin. This avoids external TVS diodes for basic overvoltage protection in low-speed status monitoring circuits.
