ETC HD29C3486

HD29C3486
Quadruple Differential Line Receivers With 3 State Outputs
ADE-205-586 (Z)
1st. Edition
Dec. 2000
Description
The HD29C3486 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 RS423A in a 16 pin package.
The circuit provides two high enable terminals and each of the terminals can control two receivers. Fail
safe design ensures that if the inputs are open the outputs will always be high.

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.
