SN74ABT16833DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16833DGGR is a dual 8-bit to 9-bit parity bus transceiver manufactured by Texas Instruments. It utilizes state-of-the-art EPIC-IIB BiCMOS design for significantly reduced power dissipation and features high-drive outputs with -32-mA IOH and 64-mA IOL capabilities. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. It incorporates a flow-through architecture optimized for PCB layout and includes distributed VCC and GND pin configurations to minimize high-speed switching noise.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates two noninverting 8-bit to 9-bit parity bus transceivers for bidirectional data communication between buses.
• Generates odd-parity bits during A-to-B transmission and checks parity during B-to-A transmission, providing active-low error flags.
• Features open-collector error flag outputs that are clocked into registers on the low-to-high transition of the clock input.
• Includes latch-up performance exceeding 500 mA per JEDEC standard JESD-17 and typical output ground bounce less than 1 V.

Buffers, Drivers, Receivers, Transceivers Applications

• Communication interfaces requiring parity error detection and correction.
• High-speed data bus systems utilizing flow-through architecture for optimized PCB layout.
• Applications demanding isolation control via independent output-enable inputs for each transceiver.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking and orientation requirements for the DGG thin shrink small-outline package before integration. Confirm that unused pins are tied high or low to prevent floating states as specified in the recommended operating conditions. Ensure the pullup resistor value for the OE pin meets the current-sinking capability of the driver to guarantee high-impedance states during power up or down.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual independent parity checking is required for 8-bit data paths. The device is suitable for designs needing high-drive outputs and minimized switching noise through distributed power pins. Consider the flow-through architecture if board space optimization is critical. Verify compatibility with the system's voltage levels and temperature requirements against the specified operating ranges.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Widebus family of Texas Instruments logic devices. It is designed using EPIC-IIB BiCMOS technology, which distinguishes it from standard CMOS counterparts by offering lower power consumption and higher drive strength. The SN74ABT16833 complements other bus transceivers in the ABT series by adding integrated parity generation and checking capabilities within a single 56-pin package.
