Product specification

74ABT16245B

74ABTH16245B

FEATURES

• 16-bit bidirectional bus interface

• Power-up 3-State

• Multiple VCC and GND pins minimize switching noise

• 3-State buffers

• Output capability: +64 mA/–32mA

• Latch–up protection exceeds 500mA per JEDEC Std 17

• Live insertion/extraction permitted

• ESD protection exceeds 2000 V per MIL STD 883 Method 3015

and 200V per Machine Model

• 74ABTH16245B incorporates bus hold data inputs which eliminate

the need for external pull-up resistors to hold unused inputs

• Bus-hold data inputs eliminate the need for external pull-up

resistors to hold unused inputs

DESCRIPTION

The 74ABT16245B high-performance BiCMOS device combines

low static and dynamic power dissipation with high speed and high

output drive.

The 74ABT16245B device is a dual octal transceiver featuring

non-inverting 3-State bus compatible outputs in both send and

receive directions. The control function implementation minimizes

external timing requirements. The device features two Output

Enable (1OE, 2OE) inputs for easy cascading and two Direction

(1DIR, 2DIR) inputs for direction control.

Two options are available, 74ABT16245B which does not have the

bus hold feature and the 74ABTH16245B which incorporates the

bus hold feature.
