SN74ABT16833DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16833DL is a dual 8-bit to 9-bit parity bus transceiver utilizing EPIC-IIB BiCMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +85°C. The device features high-drive outputs with -32-mA IOH and 64-mA IOL capabilities, alongside typical VOLP below 1 V at 5 V. Propagation delays range from 1.5 ns to 4.5 ns depending on the signal path.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (SSOP-56) against design requirements. Confirm RoHS compliance and lead finish specifications (NIPDAU). Ensure proper handling of unused pins to prevent floating states during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer requires built-in odd-parity verification. The open-collector error output allows flexible integration into diagnostic logic. Consider the flow-through pinout for simplified routing compared to standard transceivers.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the parity-error flag cleared?

The ERR output is cleared by taking the CLR input low.

What happens when both OEA and OEB are low?

Data transfers from A to B, and inverted parity is generated as a forced error condition.
