DESCRIPTION

The 74ACT16244 is a low voltage CMOS 16-BIT D-TYPE LATCH and 16 BIT BUS TRANSCEIVER with 3-STATE output non inverting fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

Both functions can be used as 16 bit or dual octal devices, so the 16 bit transceiver can be used ad 8 bit bus buffer plus 8 bit transceiver, or only 16 bit buffer in select direction.

■ HIGH SPEED: tPD = 4.8ns (TYP.) at VCC = 5V

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

■ COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.), VIL = 0.8V (MAX.)

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24mA (MIN) at VCC = 4.5V

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

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

■ FUNCTION COMPATIBLE WITH SERIES 16373 AND 16245 (244)

■ IMPROVED LATCH-UP IMMUNITY

■ IMPROVED ESD IMMUNITY
