74LVT640
3.3 V Octal transceiver with direction pin; inverting; 3-state
The 74LVT640 is an 8-bit inverting transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs
Features and benefits
3-state buffers
Wide supply voltage range from 2.7 V to 3.6 V
Overvoltage tolerant inputs to 5.5 V

Direct interface with TTL levels
IOFF circuitry provides partial Power-down mode operation
Octal bidirectional bus interface
Input and output interface capability to systems at 5 V supply
Output capability: +64 mA and -32 mA
Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
Live insertion/extraction permitted
Power-up 3-state
No bus current loading when output is tied to 5 V bus
