The ST26C32AB is a ST company's CMOS quad 3-state differential line receiver. It features low power consumption, ±0.2V sensitivity, typical propagation delay of 19ns, typical input hysteresis of 60mV, meets EIA standard RS-422, RS-423 requirements, and can be used to connect system buses.
The ST26C32AB is a quad differential line receiver designed for balanced and unbalanced digital data transmission. It features an input sensitivity of 200 mV over the common mode input voltage range of +7 V, ensuring reliable signal reception in noisy environments.
The device includes internal pull-up and pull-down resistors to prevent output oscillation on unused channels and provides a 3-state output with enable/disable functions for all four receivers. It is available in DIP-16, SO-16, and TSSOP16 packages.
