Features
General Description

#
#
#
#
#
The EL7232C 3-state drivers are particularly well suited for
ATE and microprocessor based applications. The low quiescent
power dissipation makes this part attractive in battery applications. The 2A peak drive capability, makes the EL7232C an
excellent choice when driving high speed capacitive lines, as
well. The input circuitry provides level shifting from TTL levels to the supply rails. The EL7232C is available in 8-pin P-DIP
and 8-lead SO packages.

Important Note:
All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually
performed during production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test
equipment, specifically the LTX77 Series system. Unless otherwise noted, all tests are pulsed tests, therefore TJ e TC e TA.
