PARAMETER MEASUREMENT INFORMATION
single-supply versus split-supply test circuits
Because the TLC252, TLC25L2, and TLC25M2 are optimized for single-supply operation, circuit configurations
used for the various tests often present some inconvenience since the input signal, in many cases, must be
offset from ground. This inconvenience can be avoided by testing the device with split supplies and the output
load tied to the negative rail. A comparison of single-supply versus split-supply test circuits is shown below. The
use of either circuit gives the same result.
