HD74HC563, HD74HC573 Octal Transparent Latches (with 3-state outputs) REJ03D0629-0200 (Previous ADE-205-509) Rev.
2.
00 Mar 30, 2006 Description When the latch enable (LE) input is high, the Q outputs of HD74HC563 will follow the inversion of the D inputs and the Q outputs of HD74HC573 will follow the D inputs.
When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again.
When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
Features • High Speed Operation: tpd (Data to Q, Q) = 11...
