PAC27A88
P/ACTIVE OCTAL RELAY DRIVER
Features
Octal relay driver for up to 40mA of sink current
Open drain outputs with diodes for inductive
load protection
Less than 10μA of standby current
5 KV ESD protection
Product Description
CAMDs P/Active 27A88 is an 8 channel, open drain driver with low ON resistance and integrated protection diodes for
inductive load switching. Each output can sink 40mA and all outputs may be active simultaneously. The circuit has two
VDD connections for separation of the logic (VDD
) and load (VDD
) supplies. A logic high on an input causes the
corresponding output driver to turn ON and sink current from the load. A logic low on an input causes the corresponding
output driver to turn OFF. When the switching inductive loads, the output protection diodes clamp the outputs to VDD
OUT
All inputs have pull downs to insure that the outputs are OFF when the inputs are open circuited. The inputs are fully
compatible with CMOS logic and allow the PAC27A88 to be driven directly from microcontrollers and ASICs. CAMDs
PAC27A88 is available in 20-pin small outline packages for space saving and manufacturing efficiency.

The absolute maximum ratings are limiting values, to be applied individually, beyond which the device may be permanently
damaged. Functional operation under any of these conditions is not guaranteed. Exposing the device to its absolute
maximum rating may affect its reliability.
