DESCRIPTION

The 74ACT573 is an advanced high-speed CMOS OCTAL D-TYPE LATCH with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

These 8 bit D-Type latch are controlled by a latch enable input (LE) and an output enable input (OE). While the LE inputs is held at a high level, the Q outputs will follow the data input .

■ HIGH SPEED: tPD = 5ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

   ICC = 4µA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS

   VIH = 2V (MIN.), VIL = 0.8V (MAX.)

■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

   |IOH| = IOL = 24mA (MIN)

■ BALANCED PROPAGATION DELAYS:

   tPLH = tPHL

■ OPERATING VOLTAGE RANGE:

   VCC (OPR) = 4.5V to 5.5V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 573

■ IMPROVED LATCH-UP IMMUNITY
