Product Summary
The SN74LVC573APWR octal transparent D-type latch is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVC573APWR octal transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation. The SN74LVC573APWR features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are 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.
