ST26C32ABDR

ST26C32AB CMOS quad 3-state differential line receiver Datasheet - production data The ST26C32AB has an input sensitivity of 200 mV over the common mode input voltage range of ± 7 V. The ST26C32AB features internal pull-up and pull-down resistors which prevent output oscillation on unused channels. The ST26C32AB provides an enable and disable function to all four receivers and features 3-state output with 6 mA source and sink capability. SO-16 TSSOP16 Features • CMOS design for low power • ± 0.2 V sensitivity over input common mode voltage range • Typical propagation delay: 19 ns • Typical input hysteresis: 60 mV • Input will not load line when VCC = 0 V • Meets the requirements of EIA standard RS-422, RS-423 • 3-state outputs for connection to system buses • Available in surface mount Description The ST26C32AB is a quad differential line receiver designed to meet the RS-422, RS-423 standards for balanced and unbalanced digital data transmission, while retaining the low power characteristics of CMOS.
