N74F640D规格书详情
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.
FEATURES
• High-impedance NPN base inputs for reduced loading
(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
