FEATURES
High-impedance NPN base inputs for reduced loading
(70
A in High and Low states)
Ideal for applications which require high output drive and minimal
bus loading
Octal bidirectional bus interface
3-State buffer outputs sink 64mA and source 15mA
74F620, inverting
74F623, non-inverting
DESCRIPTION
The 74F620 is an octal transceiver featuring inverting 3-State
bus-compatible outputs in both send and receive directions. The
outputs are capable of sinking 64mA and sourcing up to 15mA,
providing very good capacitive drive characteristics. The 74F623 is
a non-inverting version of the 74F620.
These octal bus transceivers are designed for asynchronous
two-way communication between data buses. The control function
implementation allows for maximum flexibility in timing.
These devices allow 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.
The dual-enable configuration gives the 74F620 and 74F623 the
capability to store data by the simultaneous enabling of OEBA and
OEAB. 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, both sets of bus lines (16 in all) will remain in their last
states.

1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V

C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
