DESCRIPTION

The 74ALVT16899 is a high-performance BiCMOS product designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V.

FEATURES

• Symmetrical (A and B bus functions are identical)

• Selectable generate parity or ”feed-through” parity for A-to-B and B-to-A directions

• Independent transparent latches for A-to-B and B-to-A directions

• Selectable ODD/EVEN parity

• Continuously checks parity of both A bus and B bus latches as ERRA and ERRB

• Open-collector ERR output

• Ability to simultaneously generate and check parity

• Can simultaneously read/latch A and B bus data

• Output capability: +64 mA/–32mA

• Latch-up protection exceeds 500mA per Jedec Std 17

• ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model

• Power up 3-State

• Power-up reset

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

• Live insertion/extraction permitted

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