74LVT373 • 74LVTH373
Low Voltage Octal Transparent Latch
with 3-STATE Outputs
General Description
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 satisfying
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.
The LVTH373 data inputs include bushold, eliminating the
need for external pull-up resistors to hold unused inputs.
These octal latches are designed for low-voltage (3.3V)
V_CC 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.
Features
s Input and output interface capability to systems at
5V V_CC
s Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH373),
also available without bushold feature (74LVT373)
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink 32 mA/64 mA
s Functionally compatible with the 74 series 373
s ESD performance:
Human-body model ! 2000V
Machine model ! 200V
Charged-device model ! 1000V
