HD26C32A

HD26C32A Quadruple Differential Line Receivers With 3 State Outputs ADE-205-575 (Z) 1st. Edition Dec. 2000 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 choise 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 sensitivity: ±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 HD26C32A Pin Arrangement IN A1 1 IN A2 2 OUT A 3 Enable 4 OUT C 5 IN C2 6 IN C1 7 GND 8 16 VCC 15 IN B1 14 IN B2 13 OUT B 12 Enable 11 OUT D 10 IN D2 9 IN D1 (Top view) Function Table Differential Input VID ≥ VTH or OPEN Enable H X VTL < VID < VTH VID ≥ VTH H X H X X H L Z X ? : : : : : High level Low level High impedance Irrelevant Indeterminate L Enable X L X L X L H Z L ?
