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 (1.65V to
3.6V) V
CC
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.
