enables (1OE, 2OE), each controlling four of the 3-state outputs.

2. Features and benefits

•Octal bus interface

•3-state buffers

•Output capability: +64 mA and -32 mA

•TTL input and output switching levels

•Input and output interface capability to systems at 5 V supply

•Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs

•Live insertion and extraction permitted

•Power-up 3-state

•No bus current loading when output is tied to 5 V bus

•Latch-up protection

•JESD78 Class II exceeds 500 mA

•ESD protection:

•HBM JESD22-A114E exceeds 2000 V

•MM JESD22-A115-A exceeds 200 V
