74HC240D,74HC244D

CMOS Digital Integrated Circuits Silicon Monolithic

74HC240D,74HC244D

1. Functional Description

•

Octal Bus Buffer

74HC240D: INVERTED, 3-STATE OUTPUTS

74HC244D: NON-INVERTED, 3-STATE OUTPUTS

2. General

The 74HC240D and 74HC244D are high speed CMOS OCTALBUS BUFFERs fabricated with silicon gate C2MOS

technology.

They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power

dissipation.

The 74HC240D is an inverting 3-state buffer and the 74HC244D are non-inverting 3-state buffers having two

active-low output enables.

These devices are designed to be used with 3-state memory address drivers, etc.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

3. Features

(1) Wide operating temperature range: Topr = -40 to 125 � (Note 1)

(2) High speed: tpd = 10 ns (typ.) at VCC = 6.0 V

(3) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25 �

(4) Balanced propagation delays: tPLH ≈ tPHL

(5) Wide operating voltage range: VCC(opr) = 2.0 V to 6.0 V

Note1 1:Operating Range spec of Topr = -40 � to 125 � is applicable only for the products which manufactured after

July 2020.

4. Packaging
