Nexperia USA Inc. 74HCT00PW,118

Overview

74HCT00PW,118 from Nexperia is a quad 2-input NAND gate IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V), 14-pin TSSOP package (SOT402-1), propagation delay of 12 ns typical at VCC = 4.5 V and CL = 50 pF, and operating temperature range of −40 °C to +125 °C. It serves as a fundamental combinational logic building block in digital control, interface buffering, and signal conditioning circuits.

For engineers reviewing the 74HCT00PW,118 datasheet, 74HCT00PW,118 pinout, 74HCT00PW,118 application, or 74HCT00PW,118 equivalent, key selection criteria include TTL-level input compatibility, guaranteed 4 mA output drive strength at VCC = 4.5 V, thermal performance in TSSOP14 (7.3 mW/K derating above 81 °C), and compliance with JEDEC JESD7A and JESD8C standards.

Technical Context

The 74HCT00PW,118 implements four independent NAND gates using CMOS technology with TTL-level input stage design, enabling direct interfacing with legacy 5 V TTL logic families without level translation. Its inputs feature integrated clamp diodes for overvoltage protection when driven by signals exceeding VCC.

Each gate exhibits symmetrical HIGH/LOW output voltage specifications (VOH ≥ 3.7 V, VOL ≤ 0.4 V at IO = ±4 mA, VCC = 4.5 V) and supports operation across 4.5 V to 5.5 V supply range, with static current consumption below 40 μA at VCC = 6.0 V and all inputs at rail.

FAQ

Can 74HCT00PW,118 operate at 3.3 V supply?

No. The 74HCT00PW,118 is specified only for 4.5 V to 5.5 V operation per JEDEC JESD8C. At 3.3 V, input thresholds (VIH = 2.0 V min) become non-compliant, and output drive degrades below guaranteed 4 mA. Use 74HC00 variants for 3.3 V systems.

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

The 74HCT00PW,118 is characterized up to 50 pF load capacitance with 12 ns typical propagation delay. Driving >75 pF increases transition time and delay unpredictably; for >100 pF loads, add a dedicated buffer stage or reduce trace length and stubs to maintain signal integrity.

Is the exposed pad on the TSSOP14 package electrically connected?

No. The exposed thermal pad in SOT402-1 is not electrically connected to any internal node. Per Nexperia documentation, it may remain floating or be connected to GND for thermal improvement, but no electrical requirement exists for soldering or grounding.

Does this part support mixed-voltage interfacing between 5 V and 3.3 V domains?

It accepts 3.3 V logic HIGH inputs safely (VIH = 2.0 V min), but its outputs swing rail-to-rail at 5 V - so direct connection to 3.3 V CMOS inputs risks overvoltage damage. Use series resistors or level translators for safe bidirectional interfacing.
