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.
