DESCRIPTION

The 74ALVCH16373 is a low voltage CMOS 16 BIT D-TYPE LATCH with 3 STATE OUTPUTS NON INVERTING fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. It is ideal for low power and very high speed 1.65 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs.

When the nLE is taken low, the nQ outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state.This device is designed to be used with 3 state memory address drivers, etc.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state.

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

■ 3.6V TOLERANT INPUTS AND OUTPUTS

■ HIGH SPEED :

tPD = 3.6 ns (MAX.) at VCC = 3.0 to 3.6V

tPD = 4.5 ns (MAX.) at VCC = 2.3 to 2.7V

tPD = 6.5 ns (MAX.) at VCC = 1.65V

■ POWER DOWN PROTECTION ON INPUTS AND OUTPUTS

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 24mA (MIN) at VCC = 3.0V

|IOH| = IOL = 18mA (MIN) at VCC = 2.3V

|IOH| = IOL = 4mA (MIN) at VCC = 1.65V

■ OPERATING VOLTAGE RANGE:

VCC(OPR) = 1.65V to 3.6V
