Dual Channel, High Speed, High Current Line Driver w/3-State 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. 3-State output 3V and 5V input compatible Clocking speeds up to 10 MHz 20 ns Switching/delay time 2A Peak drive Low, matched output impedanceÐ5X # Low quiescent currentÐ2.5 mA # Wide operating voltageÐ 4.5V--16V EL7232C EL7232C Connection Diagram Applications # Parallel bus line drivers # EPROM and PROM programming # Motor controls # Charge pumps # Sampling circuits # Pin drivers # Bridge circuits 7232 – 1 Ordering Information Part No. Temp.
