Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

74LVT573, 74LVTH573 — Low Voltage Octal Transparent Latch with 3-STATE Outputs

General Description
The LVT573 and LVTH573 consist of eight latches
with 3-STATE outputs for bus organized system applica-
tions. 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 the high
impedance state.
The LVTH573 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 LVT573 and
LVTH573 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining a low power dissipation.
