INTEGRATED CIRCUITS 74ABT620 Octal transceiver with dual enable, inverting (3-State) Product specification IC23 Data Handbook 1993 Jun 21 Philips Semiconductors Philips Semiconductors Product specification Octal transceiver with dual enable, inverting (3-State) 74ABT620 FEATURES Octal bidirectional bus interface 3-State buffers Power-up 3-State Live insertion/extraction permitted 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 DESCRIPTION The 74ABT620 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT620 device is an octal transceiver featuring inverting 3-State bus compatible outputs in both send and receive directions. The 74ABT620 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.
