74ACT573B Datasheet PDF - ST Microelectronics

●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
