74ABT623
Octal transceiver with dual enable; non-inverting; 3-state
Rev. 03 -- 22 October 2009 Product data sheet
1. General description
The 74ABT623 high performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT623 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 logic levels at the enable inputs (pins OEAB and 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 pins 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 the bus lines will remain at their last states. The 8-bit codes appearing on the two sets of buses will be identical.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 C. For SO20 package: Ptot derates linearly with 8 mW/K above 70 C. For SSOP20 and TSSOP20 package: Ptot derates linearly with 5.5 mW/K above 60 C.

This parameter is valid for any VCC between 0 V and 2.1 V, with a transition time of up to 10 ms. From VCC = 2.1 V to VCC = 5 V 10 %, a transition time of up to 100 ms is permitted. Not more than one output should be tested at a time, and the duration of the test should not exceed one second. This is the increase in supply current for each input at 3.4 V.
