M74HCT573 is a high speed CMOS 8-bit D-type latch with 3-state outputs.
The M74HCT573 is a high-speed CMOS octal latch with 3-state outputs fabricated with silicon gate C2MOS technology. It is designed to directly interface HSCMOS systems with TTL and NMOS components. The device is controlled by a latch enable input (LE) and an output enable input (OE).
| Operating Temperature | -55 to 125 °C |
|---|---|
| Propagation Delay (Typical) | 21 ns |
| Output Current (IOH) | 6 mA |
| Package Types | DIP, SOP, TSSOP |
While the LE input is held at a high level, the Q outputs will follow the data input precisely.
When the OE input is at a high level, the outputs will be in a high impedance state.
Yes, it is compatible with TTL outputs with a minimum input voltage of 2V.
