DS8923AM Description

Short technical summary and product information.

The DS8923AM from Texas Instruments is a dual differential line driver and receiver pair, designed to meet EIA RS-422 standards. This transceiver operates with a supply voltage range of 4.5V to 5.5V and features a typical propagation delay of 12 ns with an output skew of ±0.5 ns. It provides complementary driver outputs and a receiver sensitivity of 200 mV over a ±7V common mode range.

Key features include receiver input hysteresis of 70 mV typical, which enhances noise margin for slowly changing input waveforms. The device also incorporates input fail-safe circuitry, ensuring the output assumes a logical one state if receiver inputs are open. The DS8923AM is designed for surface mount applications and comes in a 16-SOIC package.

This transceiver is compatible with TTL and CMOS logic levels. It is suitable for applications requiring robust differential signaling, such as disk drive standards like ST506, ST412, and ESDI. The device also features glitch-free power up/down operation, ensuring stable transmission lines during system power transitions.
