M74HC259TTR概述

8位可寻址锁存 8 BIT ADDRESSABLE LATCH

DESCRIPTION

The M74HC259 is an high speed CMOS 8 BIT ADDRESSABLE LATCH fabricated with silicon gate C2MOS technology.

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

■ HIGH SPEED :

tPD = 20 ns TYP. at VCC = 6V

■ LOW POWER DISSIPATION:

ICC =4µAMAX. at TA=25°C

■ HIGH NOISE IMMUNITY:

VNIH = VNIL = 28 % VCC MIN.

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4mA MIN

■ BALANCED PROPAGATION DELAYS:

tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE:

VCC OPR = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 259
