HD26C32A
Quadruple Differential Line Drivers With 3 State Outputs
REJ03D0293–0200Z
(Previous ADE-205-575 (Z))
Rev.2.00
Jul.16.2004 Description
The HD26C32A provides differential line receivers which realize low power dissipation by CMOS process. The device has four receivers which meet the requirements of EIA standard RS-422A and RS-423A in a 16 pin package.
The enable function is common to all four receivers and offers a choi of active high or active low inputs. Fail safe design ensures that if the inputs are open the outputs will always be high.
Features
•Low power dissipation with CMOS process
•Meets EIA standard RS-422A/423A
•Input nsitivity: ±0.2V (In the range of ±7 V of common mode input voltage)
•Propagation delay time: 19 ns typ
•Input hysteresis width: 60 mV typ
•Three state outputs
•Differential Inputs are includes fail safe circuit
•Power up and power down protection
•Pin to pin compatible with HD26LS32/32A

Notes: 1.The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two
of which may be realized at the same time.
2.All voltage values except for differential input voltage are with respect to network ground terminal.
3.Differential input voltage is measured at the noninverting input with respect to the corresponding inverting
input.
