HD29050 Dual Differential Line Drivers/ReceiversWith 3 State Outputs ADE-205-034A (Z) 2nd. Edition Mar. 1993 Description The HD29050 features differential line drivers/receivers with three state output designed to meet the spec of EIA RS-422A and 423A. Each device has two drivers/receivers in a 16 pin package. The device becomes in enable state when active high for a driver and active low for a receiver. Features Driver • Built in current restriction when short circuit • Power up/down protection. • High output current IOH = –40 mA IOL = 40 mA Receiver • Input hysteresis (Typ. 50 mV) • In phase input voltage ±200 mV of input sensitivity in the range –7 to +12 V.
