ATMEL E5130A Low voltage cmos driver circuit Datasheet

e5130
Low Voltage CMOS Driver Circuit
Description
The e5130 contains 4 independent driver outputs with an
ON resistance of typ. 25 (15 ) tor the P-channel
output transistors and typ. 20 (13 ) 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.

Absolute Maximum Ratings
Absolute maximum ratings define parameter limits which, it 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.
