UC5172

UC5172 Octal Line Driver FEATURES Eight Single-Ended Line Drivers in One Package Meets Standards EIA232E/CCITT V.28, and EIA423A/CCITT V.10/X.26 Single External Resistor Controls Slew Rate Wide Supply Voltage Range Tri-State Outputs Output Short-Circuit Protection Low Power Consumption 2kV ESD Protection on all Pins EOS on all Output Pins 35V under all Output Conditions High Current Output for Long Line Drive, Exceeds Standards CONNECTION DIAGRAMS N PACKAGE (TOP VIEW) DESCRIPTION The UC5172 is a single-ended octal line driver designed to meet both standard modem control applications (EIA232E/V.28), and long line drive applications (EIA423A/V.10/X.26). The slew rate for all 8 drivers is controlled by a single external resistor. The slew rate and output levels are independent of the power variations. The UC5172 has high output current, and current balance for long line drive applications. EOS - Output parasitic SCRs powered on and off are 35V, well above signal levels, allowing protection devices to work. Inputs are compatible TTL+MOS logic families and are diode protected against negative transients. FUNCTIONAL TABLE INPUTS EN 0 0 1 Note 2: Minimum output swings.
