The M74HC563 is an high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with silicon gate C2MOS technology.
The M74HC563 is a high-speed CMOS octal latch with 3-state outputs fabricated with silicon gate CMOS technology. It is 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 inversely; when LE is taken low, the outputs latch inversely at the logic level of the D input. The device features a wide operating voltage range from 2V to 6V and is pin and function compatible with the 74 series 563.
| Operating Voltage Range | 2V to 6V |
|---|---|
| Supply Voltage | -0.5 to +7 V |
| Operating Temperature | -55 to 125 °C |
| Propagation Delay (Typical) | 13ns |
| Output Leakage Current | 4uA |
| Input Capacitance | 10 pF |
While the LE input is held at a high level, the Q outputs will follow the data input inversely.
When the OE input is at a low level, the eight outputs will be in a normal logic state (high or low logic level).
Yes, it is pin and function compatible with the 74 series 563.
