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