description
This octal transparent D-type latch is designed for
2.7-V to 3.6-V VCC operation.
The SN74LVC573 features 3-state outputs designed specifically for driving highly capacitive or relatively
low-impedance loads. It is particularly suitable for implementing buffer registers, input/output (I/O) ports,
bidirectional bus drivers, and working registers.
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 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 a 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 the need for 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.
The SN74LVC573 is characterized for operation from – 40
°C to 85°C.
