FEATURES
Octal bidirectional bus interface
3-State buffers
Output capability: +64mA/-32mA
TTL input and output switching levels
Input and output interface capability to systems at 5V supply
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
Live insertion/extraction permitted
Power-up 3-State
No bus current loading when output is tied to 5V bus
Latch-up protection exceeds 500mA per JEDEC Std 17
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
DESCRIPTION
The LVT640 is a high-performance BiCMOS product designed for
VCC operation at 3.3V.
This device is an octal transceiver featuring inverting 3-State bus
compatible outputs in both send and receive directions. The control
function implementation minimizes external timing requirements.
The device features an Output Enable (OE) input for easy cascading
and a Direction (DIR) input for direction control.
