This document describes the features and characteristics of TL6518 DM7446A DM5447A DM7447A BCD to 7-segment decoders/drivers, including circuits with active-low outputs, full ripple-blanking input/output controls, lamp test input, automatic leading and trailing zero-blanking control, etc. The products have features such as lamp intensity modulation capability, open-collector outputs for driving indicators directly, lamp test provision, leading-trailing zero suppression, etc.
This document is a technical datasheet for the DM7446A, DM5447A, and DM7447A integrated circuits. These devices are BCD to 7-segment decoders/drivers designed with active-low outputs intended for driving common-anode LEDs or incandescent indicators directly.
| Low Level Output Current (a thru g) | 40 mA |
|---|---|
| Propagation Delay Time | 100 ns |
The devices feature active-low outputs designed for driving common-anode LEDs or incandescent indicators directly.
Yes, lamp test (LT) may be performed at any time when the BI/RBO node is at a high logic level.
