SN74HCT573N

Latches Overview

The SN74HCT573N is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the HCT logic series. It features eight independent D-type latches with non-inverting outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 20-pin DIP package for through-hole mounting. Electrical characteristics include a propagation delay of 52 ns at 4.5 V and 47 ns at 5.5 V, with a maximum static current of 8 uA. Output drive capabilities provide a low-level output current of 32 mA and a high-level output current of -6 mA. The component supports an operating temperature range from -40°C to +85°C.
