INTEGRATED CIRCUITS 74LVC623A Octal transceiver with dual enable (3-State) Product specification 1998 Jul 29 Philips Semiconductors Product specification Octal transceiver with dual enable (3-State) FEATURES 74LVC623A DESCRIPTION • Wide supply voltage range of 1.2V to 3.6V • In accordance with JEDEC standard no. 8-1A • Flow-through pin-out architecture • CMOS low power consumption • Inputs accept voltages up to 5.5V • Direct interface with TTL levels • Output drive capability 50 transmission lines @ 85°C The 74LVC623A is a high performance, low-power, low-voltage Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. The 74LVC623A is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. This octal bus transceiver is designed for asynchronous two-way communication between data buses. The control function implementation allows 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 levels at the enable inputs (OEAB, OEBA). The enable inputs can be used to disable the device so that the buses are effectively isolated. The dual enable function configuration gives this transceiver the capability to store data by simultaneous enabling of OEAB and OEBA. Each output reinforces its input in this transceiver configuration. Thus, when both control inputs are enabled and all other data sources to the two sets of the bus lines are at high impedance OFF-state, both sets of bus lines will remain at their last states. The 8-bit codes appearing on the two sets of buses will be identical. The ‘623A’ is identical to the ‘620A’ but has true (non-inverting) outputs.
