DESCRIPTION

The 74VHCT244A is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. G enable input governs four BUS BUFFERs.

This device is designed to be used with 3 state memory address drivers, etc.

Power down protection is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V since all inputs are equipped with TTL threshold.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 5.4 ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

ICC = 4 μA (MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS:

VIH = 2V (MIN.), VIL = 0.8V (MAX)

■ POWER DOWN PROTECTION ON INPUTS & OUTPUTS

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 8 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

■ LOW NOISE: VOLP = 0.9V (MAX.)
