This document is a technical datasheet for the 54ACT11821 and 74ACT11821 devices, which are 10-bit bus-interface flip-flops featuring 3-state outputs. These components are designed to drive highly-capacitive loads or relatively low-impedance loads, making them suitable for wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers.
| Operating Temperature (Military) | -55°C to 125°C |
|---|---|
| Setup Time (Data before CLK) | 25 ns |
| Hold Time (Data after CLK) | 15 ns |
The device has a typical latch-up immunity of 500-mA at 125°C.
The continuous output current is rated for +50 mA or -50 mA.
