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.
