74LVT373, 74LVTH373
Low Voltage Octal Transparent Latch with 3-STATE Outputs
Features
General Description
■ Input and output interface capability to systems at
The LVT373 and LVTH373 consist of eight latches with
3-STATE outputs for bus organized system applications.
The latches appear transparent to the data when Latch
Enable (LE) is HIGH. When LE is LOW, the data satisfy-
ing the input timing requirements is latched. Data
appears on the bus when the Output Enable (OE) is
LOW. When OE is HIGH, the bus output is in a high
impedance state.
5V V
CC
■ Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH373),
also available without bushold feature (74LVT373)
■ Live insertion/extraction permitted
■ Power Up/Down high impedance provides glitch-free
bus loading
The LVTH373 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
■ Outputs source/sink –32 mA/+64 mA
■ Functionally compatible with the 74 series 373
■ ESD performance:
These octal latches are designed for low-voltage (3.3V)
– Human-body model > 2000V
– Machine model > 200V

applications, but with the capability to provide a TTL

interface to a 5V environment. The LVT373 and
LVTH373 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
– Charged-device model > 1000V
