STMICROELECTRONICS  M74HC259B1R  芯片, 74HC CMOS逻辑器件

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
