IOTORO! —— @& m LA Mc34050 Dual EIA-422/423 Transceivers ‘The MC34050/51 are dual transceivers which comply with EIA Standards EA-2 (Balerced Ine) and EIA-423 (Unbalanced line). Each device DUAL EIA-422/423 contains two drivers and two receivers. ‘The MC34050 has a DRIVER ENABLE (for both drivers) and a TRANSCEIVERS RECEIVER ENABLE (for both receivers). Connecting the two ENABLES together provides Driver-to-Receiver switching from a single line. SEMICONDUCTOR ‘The MC34051 has a DRIVER ENABLE for each driver. The two receivers TECHNICAL DATA are permanently enabled. The Driver inputs, Receiver outputs, and Enable inputs are 74LS TTL compatible. z D SUFFIX © Two Independent Drivers and Receivers Per Package Lf PLASTIC PACKAGE © 3-State Outputs CASE 751B (80-16) © Single 5.0 V Supply © Internal Hysteresis (50 mV Typical) on Receivers P SUFFIX © Receivers Provide Fait-Sate Function.
