The M74HC533 is an high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with silicon gate C2MOS technology.
The M74HC533 is a high-speed CMOS octal latch with 3-state outputs fabricated with silicon gate CMOS technology. It is an 8-bit D-type latch controlled by a latch enable input (LE) and an output enable input (OE). While the LE input is held high, the Q outputs follow the data input; when LE is taken low, the outputs latch at the logic level of the D input. The device features symmetrical output impedance and balanced propagation delays.
| Supply Voltage Range | 2V to 6V |
|---|---|
| Propagation Delay (Typical) | 12ns |
| Low Power Dissipation | 4uA |
| Operating Temperature | -55 to 125 °C |
| Number of Latches | 8 |
While the LE input is held at a high level, the Q outputs will follow the data input. When the LE is taken low, the Q outputs will be latched at the logic level of the D input.
Yes, it is pin and function compatible with the 74 series 533.
