DESCRIPTION
B6
B7
The 74F640 is an octal transceiver featuring inverting 3-State bus
compatible outputs in both transmit and receive directions. The B
port outputs are capable of sinking 64mA and sourcing 15mA,
providing very good capacitive drive characteristics. The device
features an Output Enable (OE) input for easy cascading and
Transmit/Receiver (T/R) input for direction control. The 3-State
outputs, B0–B7, have been designed to prevent output bus loading if
the power is removed from the device.

NOTES:
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 = 5V, T = 25°C.

3. Not more than one output should be shorted at a time. For testing I , the use of high-speed test apparatus and/or sample-and-hold
OS
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 tests should be performed last.
