74VCXH16373

Low Voltage 16-Bit Transparent Latch with Bushold

General Description

The VCXH16373 contains sixteen non-inverting latches

with 3-STATE outputs and is intended for bus oriented

applications. The device is byte controlled. The flip-flops

appear to be transparent to the data when the Latch

Enable (LE) is HIGH. When LE is LOW, the data that meets

the setup time is latched. Data appears on the bus when

the Output Enable (OE) is LOW. When OE is HIGH, the

outputs are in a high impedance state.

The VCXH16373 data inputs include active bushold cir-

cuitry, eliminating the need for external pull-up resistors to

hold unused or floating data inputs at a valid logic level.

The 74VCXH16373 is designed for low voltage (1.2V to

3.6V) VCC applications with output compatibility up to 3.6V.

The 74VCXH16373 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.
