74VCXH162373
Low Voltage 16-Bit Transparent Latch with Bushold
and 26Ω Series Resistors in Outputs
General Description
The VCXH162373 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 out-
puts are in a high impedance state.
The VCXH162373 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 VCXH162373 is also designed with 26Ω series resis-
tors in the outputs. This design reduces line noise in appli-
cations such as memory address driver, clock drivers and
bus transceivers/transmitters.
The 74VCXH162373 is designed for low voltage (1.65V to
3.6V) VCC applications with output compatibility up to 3.6V.
The 74VCXH162373 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
