SN74ABT16833DLRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16833DLRG4 is a dual 8-bit to 9-bit parity bus transceiver utilizing Texas Instruments' EPIC-IIB BiCMOS technology. It features two independent non-inverting transceivers with integrated odd-parity generation and checking capabilities. The device includes dedicated parity I/O pins (1PARITY, 2PARITY) and open-collector error flag outputs (1ERR, 2ERR). Designed for high-speed data communication, it offers high-drive outputs of -32 mA IOH and 64 mA IOL. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package materials information to confirm tape and reel specifications. Ensure compatibility with the SSOP-56 footprint and check moisture sensitivity level ratings before assembly. Confirm that the RoHS compliance status matches project requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-channel parity checking is required alongside standard bus transceiving functions. The EPIC-IIB design provides significantly reduced power dissipation compared to older technologies. Consider the flow-through architecture if minimizing trace length and optimizing board space are critical design constraints.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the parity-error flag cleared?

The error flag register is cleared by taking the clear input (1CLR or 2CLR) low.

What happens when both output-enable inputs are low?

When both OEA and OEB are low, data transfers from the A bus to the B bus, and inverted parity is generated as a forced error condition.
