Description

MC7447ATHX1000NB is a Motorola/ON Semiconductor BCD-to-7-segment decoder/driver (MC7447A family). It decodes a 4-bit BCD input (0–9) into seven outputs (a–g) that drive a common-anode LED display. The outputs are open-collector, so segments light when the output sinks current (typically via a resistor and a common-anode supply). Features include lamp test (LT), blanking input (BI), and ripple-blanking inputs (RBI) for multi-digit displays. Operates at about 4.75–5.25 V with TTL-compatible inputs. The “ATHX1000NB” suffix denotes a specific packaging/lot variant, while the function remains straightforward: low-cost digit decoding. Typical applications include digital clocks, counters, calculators, and instrumentation displays using 7-segment readouts.

Features

Here are the key features of MC7447ATHX1000NB:
- 4-bit BCD to 7-segment decoder/driver for common-anode LED displays.
- Seven open-collector outputs (a–g) that sink current; requires pull-up resistors.
- Lamp Test (LT) input to illuminate all segments.
- Blanking Input (BI) to extinguish the display.
- Ripple-Blanking Input (RBI) and Ripple-Blanking Output (RBO) for cascading digits and leading-zero suppression.
- TTL-compatible inputs; designed for standard 5 V operation.
- Suitable for multi-digit displays with easy interfacing to microcontrollers.
- Automotive/extended-temp variant in the ATHX1000NB family (check datasheet for exact temp range and packaging).

Pinout

- Pin count: 16 pins (DIP-16/SOP-16).
- Function: BCD-to-7-segment decoder/driver with open-collector outputs for common-anode LED displays. It takes a 4-bit BCD input (A–D) and outputs the seven segments (a–g). Includes display-control pins such as Lamp Test (LT) and Blanking/Ripple-Blanking (BI/RBO). Outputs are open-collector and require pull-up resistors to drive the LEDs.

Manufacturer

Manufacturer: NXP Semiconductors (the legacy Motorola MC74xx TTL family; Motorola’s semiconductors were acquired and are now part of NXP).
What kind of company: NXP Semiconductors is a Dutch multinational that designs and manufactures semiconductor integrated circuits and related technologies for automotive, industrial, and consumer applications.

Application

Applications of MC7447ATHX1000NB (BCD-to-7-seg driver for common-anode LEDs):
- Drive common-anode 7-segment LED displays from BCD inputs
- Digital clocks and time displays
- Calculators and numeric displays
- Digital panel meters, counters, and frequency meters
- Instrumentation, test equipment readouts, and measurement displays
- Consumer electronics displays, timers, and alarms
- Any LED display pendant or indicator requiring a decoder/driver
Notes: outputs are open-collector and sink current; connect segments to Vcc through current-limiting resistors.

Package

16‑pin plastic DIP (through‑hole) package.
