Nexperia USA Inc. 74AHC00PW,118

Overview

74AHC00PW,118 from Nexperia is a quad 2-input NAND gate IC in TSSOP14 package, operating from 2.0 V to 5.5 V supply, featuring overvoltage-tolerant inputs (up to 5.5 V), Schmitt-trigger inputs for noise immunity, and specified for -40 °C to +125 °C industrial temperature range. It serves as a level-translating logic gate in mixed-voltage digital systems such as microcontroller I/O expansion and bus interface conditioning.

For engineers reviewing the 74AHC00PW,118 datasheet, 74AHC00PW,118 pinout, 74AHC00PW,118 application, or 74AHC00PW,118 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V/5 V, output drive capability (±8 mA), CMOS-level compatibility, and thermal performance in TSSOP14 packaging.

Technical Context

This device implements four independent 2-input NAND logic functions with identical electrical behavior per gate. Each input accepts CMOS-level signals and tolerates up to 5.5 V regardless of VCC, enabling use as a bidirectional voltage translator between 3.3 V and 5 V domains.

Propagation delays are characterized across VCC (3.0–5.5 V) and load capacitance (15–50 pF), with typical tpd of 3.2 ns at 5 V/15 pF and 4.5 ns at 5 V/50 pF. Static parameters include VIH = 3.85 V (min at VCC = 5.5 V), VOL = 0.36 V (max at IO = 8 mA), and ICC ≤ 40 μA (max at VCC = 5.5 V).

FAQ

Is 74AHC00PW,118 pin-compatible with 74HC00?

Yes, it is functionally and pinout-compatible with standard 74HC00 in TSSOP14, but offers wider supply range (2.0–5.5 V vs. 2.0–6.0 V), improved overvoltage tolerance (5.5 V input rating), and enhanced ESD protection (HBM > 2000 V). No PCB redesign is needed for drop-in replacement in most 74HC00 applications.

Can 74AHC00PW,118 safely interface a 5 V sensor output with a 3.3 V microcontroller?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, allowing direct connection of 5 V sensor outputs to the gate inputs while VCC = 3.3 V. The output swings rail-to-rail (0 V to 3.3 V), ensuring compatible logic levels for the MCU's GPIO.

What is the maximum capacitive load this device can drive reliably?

It is characterized up to 50 pF load capacitance with guaranteed propagation delay (e.g., 4.5 ns max at 5 V/50 pF). For loads exceeding 50 pF, rise/fall times increase and may require buffer staging; total output current remains within ±8 mA limit regardless of CL.

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

No - all inputs have Schmitt-trigger action and defined logic thresholds. However, floating inputs are not recommended; unused inputs should be tied to VCC or GND to prevent increased ICC and potential oscillation due to noise coupling.
