1.4Amp, 2MHz Step-Up Switching Regulator with Soft-Start

Description The SC4502/SC4502H is a high-frequency current-mode step-up switching regulator with an integrated 1.4A power transistor. Its high switching frequency (program mable up to 2MHz) allows the use of tiny surface-mount external passive components. Features ‹Low saturation

Strobed hex inverter/buffer

The HEF4502B consists of six inverter/buffers with 3-state outputs. When the output enable input (EO) is HIGH all six outputs (O1to O6) are in the high impedance OFF-state. When the enable input (E) is HIGH all six outputs are switched to LOW. The outputs have a 2-TTL load drive capability.
