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