2 / 10 page Philips Semiconductors Product specification 74ABT623 Octal transceiver with dual enable, non-inverting (3-State) 2 1998 Jan 16 853–1459 18866 FEATURES • Octal bidirectional bus interface • 3-State buffers • Power-up 3-State • Output capability: +64mA/–32mA • Latch-up protection exceeds 500mA per Jedec Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model • Inputs are disabled during 3-State mode DESCRIPTION The 74ABT623 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT623 device is an octal transceiver featuring non–inverting 3-State bus compatible outputs in both send and receive directions. The 74ABT623 is designed for asynchronous two-way communication between data buses. The control function implementation allows for maximum flexibility in timing. This device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic levels at the Enable inputs (OEBA and OEAB). The Enable inputs can be used to disable the device so that the buses are effectively isolated.
