QUAD RS-422, RS-423 CMOS Differential Line Receiver
June 1997–3
FEATURES D Pin-to-Pin Compatible with National DS26C32C D Low Power CMOS Design D Three-State Outputs with Enable Pin D Meets the EIA RS-422 Requirements D Low Propagation Delays D High Speed
GENERAL DESCRIPTION The ST26C32 is a CMOS quad differential line receiver designed to meet the standard RS-422, RS-423 requirements. The ST26C32 has an input sensitivity of 200mv over the common mode input voltage range of ±7V. To improve noise margin and output stability for slow changing input signal, special hysteresis is built in the ST26C32 circuit. The ST26C32 is a high speed line receiver designed to operate with MFM / RLL controllers and hard disk drives as well as RS-422, and RS-423 differential applications. ST26C32 provides TTL compatible outputs to interface with standard 74LS and CMOS design environments. ST26C32 is suitable for low power 5V operation.
