General Description
74ACT240 General Description
The ACT240 is an advanced CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications mantaining high speed operation similar to equivalent Bipolar Schottky TTL.
G control output governs four BUS BUFFERs.
This device is desibned to be used with 3 state memory address drivers, etc. The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
