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.

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 T
