HD26C32A Line Receiver Applications
The HD26C32A is a line receiver that meets the EIA RS-422A and RS-423A conditions. It has a high in-phase input
voltage range, both positive and negative, enabling highly reliable transmission to be performed even in noisy
environments.
Its main features are listed below.
As shown by the logic diagram, the enable function is common to all four drivers, and either active-high or active-low
input can be selected.
When exchange is carried out using a party line system, it is better to keep the receiver input bias current constituting
the driver load small, as this allows more receivers to be connected.
