Description
The e5130 contains 4 independent driver outputs with an ON resistance of typically 25 /g87 (15 /g87) for the P-channel output transistors and typically 20 /g87 (13 /g87) for the N-channel output transistors at a supply voltage of 1.5 V (3 V). To obtain a fast transi- tion of the outputs even for slow rise/fall time input signals, all digital inputs (IN1 to IN4) have a Schmitt-trigger characteristic with a hysteresis of typically 50 mV. If a higher driving capability is needed, all inputs and outputs may be connected in par- allel. In this case the rise/fall time of the input signals IN1 to IN4 must be less than 200 ns. Due to the fast switching characteristic of the tri-statable output drivers, the circuit is also suited as a low-voltage bus driver. Low Voltage CMOS Driver Circuit e5130

4730A–CLOCK–07/03 Absolute Maximum Ratings Absolute maximum ratings define parameter limits which, if exceeded, may permanently change or damage the device. All inputs and outputs on circuits are highly protected against electrostatic discharges. However, precautions to minimize build-up of electrostatic charges during handling are recommended. The circuits are protected against supply voltage reversal for typically 5 minutes, if the current is limited to 120 mA.
