74LVT16373 • 74LVTH16373
Low Voltage 16-Bit Transparent Latch
with 3-STATE Outputs
General Description
The LVT16373 and LVTH16373 contain sixteen non-invert-
ing latches with 3-STATE outputs and is intended for bus
oriented applications. The device is byte controlled. The
flip-flops appear 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 LVTH16373 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These latches are designed for low-voltage (3.3V) VCC
applications, but with the capability to provide a TTL inter-
face to a 5V environment. The LVT16373 and LVTH16373
are fabricated with an advanced BiCMOS technology to
achieve high speed operation similar to 5V ABT while
maintaining a low power dissipation.
Features
s Input and output interface capability to systems at
