Product details

Switching speed and drive

The SN74AHCT00N: Maximum propagation delay is 7.9ns at 5V with a 50pF load, which sets the timing budget for glitch-free data paths in clocked systems. The symmetrical 8mA source and sink output current drives standard logic inputs and lightly loaded buses without external buffers.

Package and temperature grade

Housed in a 14-pin PDIP (0.300" width, 7.62mm body), the through-hole package suits prototyping, breadboard work, and legacy board repairs where a soldered DIP is preferred over a surface-mount part.

Quiescent current and compliance

Quiescent current draws a maximum of 2 µA, keeping the static power contribution negligible in battery-backed or always-on logic sections.

Frequently asked questions

What is the propagation delay of SN74AHCT00N?

Maximum propagation delay is 7.9ns at 5V supply with a 50pF load. This figure sets the timing margin for data setup and hold in synchronous designs.

Can I use SN74AHCT00N as a replacement for 74HC00?

The SN74AHCT00N is a direct functional equivalent to the 74HC00 — both are quad 2-input NAND gates in the same 14-DIP pinout. The AHCT variant uses TTL-compatible input thresholds (0.8V low, 2V high) versus the HC family's CMOS thresholds (0.5V to 1.8V low, 1.5V to 4.2V high), so verify the driving logic levels in your specific circuit before substituting.

What is the pinout of SN74AHCT00N?

The SN74AHCT00N follows the standard 14-pin DIP pinout for a quad 2-input NAND gate: pin 7 is GND, pin 14 is VCC. Each gate has inputs on pins 1-2 (gate 1), 4-5 (gate 2), 9-10 (gate 3), 12-13 (gate 4), with outputs on pins 3, 6, 8, and 11 respectively.
