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 applica-
tions 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 lev-
els to the supply rails The EL7232C is available in 8-pin P-DIP
and 8-lead SO packages
