UPD74HC42GS-T2** is a BCD-to-decimal decoder IC manufactured by **NEC**.

The UPD74HC42GS-T2 is a BCD-to-decimal decoder IC manufactured by NEC. Below are its key specifications, descriptions, and features:

Specifications:

  • Manufacturer: NEC
  • Part Number: UPD74HC42GS-T2
  • Technology: High-Speed CMOS (74HC Series)
  • Function: BCD-to-Decimal Decoder
  • Supply Voltage (VCC): 2V to 6V
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: SSOP (Shrink Small Outline Package)
  • Pin Count: 16
  • Logic Family: 74HC

Descriptions:

  • Decodes a 4-bit Binary-Coded Decimal (BCD) input into one of ten active-low outputs (0 to 9).
  • Invalid BCD inputs (1010 to 1111) result in all outputs remaining high (inactive).
  • Designed for high-speed operation with low power consumption.

Features:

  • High-Speed CMOS Logic – Compatible with TTL levels.
  • Low Power Consumption – Suitable for battery-operated devices.
  • Wide Operating Voltage Range – 2V to 6V.
  • Active-Low Outputs – Each output corresponds to a BCD input (0-9).
  • Schmitt-Trigger Inputs – Improved noise immunity.
  • ESD Protection – Enhanced reliability.

This IC is commonly used in digital systems for display driving, address decoding, and control applications.

(Note: Always refer to the official datasheet for detailed electrical characteristics and application guidelines.)
