FEATURES
74F640
PIN CONFIGURATION
• High-impedance NPN base inputs for reduced loading
20 VCC
T/R 1
(70µA in High and Low states)
• Ideal for applications which require high-output drive and minimal
bus loading
• Inverting version of 74F245
• Octal bidirectional bus interface
• 3-State outputs sink 64mA and source 15mA
DESCRIPTION
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 VCC = 5V, Tamb = 25°C.
3. Not more than one output should be shorted at a time. For testing IOS, 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, IOS tests should be performed last.
