GENERAL DESCRIPTION

The ST34C86 is a CMOS quad differential line receiver

designed to meet the standard RS-422, RS-423

requirements. The ST34C86 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

ST34C86 circuit. The ST34C86 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. ST34C86 provides TTL

compatible outputs to interface with standard 74LS and

CMOS design environments. ST34C86 is suitable for low

power 5V operation.
