74LVC573A
Description
OCTAL TRANSPARENT D-TYPE LATCH WITH 3 STATE OUTPUTS
A
Pin Assignments
The 74LVC573A provides eight transparent D-type latches. While
the latch-enable (LE) input is high, the Q outputs follow the data (D)
inputs. When LE is taken low, the Q outputs are latched at the logic
levels set up at the D inputs. A buffered output-enable (OE) input
can be used to place the eight outputs in either a normal logic state
(high or low logic levels) or the high-impedance state. In the high-
impedance state, the outputs neither load nor drive the bus lines
significantly. The high-impedance state and increased drive provide
the capability to drive bus lines without interface or pullup
components. OE does not affect the internal operations of the
latches. Old data can be retained or new data can be entered while
the outputs are in the high-impedance state.
These devices feature inputs and outputs on opposite sides of the
package that facilitate printed circuit board layout. The device is
designed for operation with a power supply range of 1.65V to 3.6V.

The inputs are tolerant to 5.5V allowing this device to be used in a
mixed voltage environment. The device is fully specified for partial
power down applications using IOFF. The IOFF circuitry disables the
output preventing damaging current backflow when the device is
powered down.
Features
Supply Voltage Range from 1.65V to 3.6V
Sinks or Sources 24mA at VCC = 3V
CMOS Low Power Consumption
IOFF Supports Partial-Power Down Operation
Inputs or Outputs Accept Up to 5.5V
Inputs Can Be Driven by 3.3V or 5V Allowing for Mixed Voltage
Applications
Schmitt Trigger Action at All Inputs
Typical VOLP (Quiet Output Ground Bounce) Less than 0.8V
with VCC = 3.3V and TA = +25°C
Typical VOHV (Quiet Output Dynamic VOH) Greater than 2.0V
with VCC = 3.3V and TA = +25°C
ESD Protection Tested per JESD 22
Exceeds 200-V Machine Model (A115)
Exceeds 2000-V Human Body Model (A114)
Exceeds 1000-V Charged Device Model (C101)
Latch-Up Exceeds 250mA per JESD 78, Class I
All devices are:
Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
