Product Details

Description



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

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.


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.

The 74ALVT16899 is a 16-bit to 16-bit parity transceiver with separate transparent latches for the A bus and B bus. Either bus can generate or check parity. The parity bit can be fed-through with no change or the generated parity can be substituted with the SEL input. 

The 74ALVT16899 features independent latch enables for the A and B bus latches, a select pin for ODD/EVEN parity, and separate error signal output pins for checking parity.
