74ACT244B Datasheet PDF - ST Microelectronics

●DESCRIPTION

●The ACT244 is an advanced CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron

●silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications

●mantaining high speed operation similar to equivalent Bipolar Schottky TTL.

●■ HIGH SPEED: tPD= 4.5 ns (TYP.) at VCC=5V

●■ LOW POWER DISSIPATION: ICC=8µA (MAX.) at TA=25oC

●■ COMPATIBLEWITH TTL OUTPUTS VIH =2V(MIN),VIL = 0.8V(MAX)

●■ 50ΩTRANSMISSION LINE DRIVING CAPABILITY

●■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH|=IOL= 24 mA (MIN)

●■ BALANCED PROPAGATION DELAYS: tPLH≅tPHL

●■ OPERATING VOLTAGE RANGE: VCC(OPR) = 4.5V to 5.5V

●■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 244

●■ IMPROVED LATCH-UP IMMUNITY
