Posted on by pinout

Part Number: 7447, DM7447A

Description

BCD to 7-Segment Decoders/Drivers

Manufacturer: Fairchild Semiconductor

General Description

The DM7446A and DM7447A feature active-LOW outputs designed for driving common-anode LEDs or incandescent indicators directly. All of the circuits have full ripple-blanking input/output controls and a lamp test input. Segment identification and resultant displays are shown on a following page. Display patterns for BCD input counts above nine are unique symbols to authenticate input conditions.

IR2153S datasheet

Description

The IR2153D(S) are an improved version of the popular IR2155 and IR2151 gate driver ICs, and incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer.

The IR2153 provides more functionality and is easier to use than previous ICs.
