Description

The DM7406 is a hex inverting buffer IC featuring high-voltage open-collector outputs, typically housed in DIP or SOP packages for TTL logic applications. Each of its six independent inverters provides strong sink capability and allows interfacing with higher voltage loads through external pull-up resistors. It is commonly used in level shifting, driving lamps or relays, and general-purpose logic inversion in digital systems.

Features

  • Six independent inverting buffers
  • Open-collector outputs for flexible voltage interfacing
  • High-voltage output capability up to 30V
  • Compatible with standard TTL logic levels
  • High current sinking capability
  • Suitable for driving LEDs, relays, and other loads

Pinout

Design Notes

  • External pull-up resistors are mandatory for proper output logic levels
  • Pull-up resistor value should be selected based on required speed and load current
  • Suitable for level shifting between TTL and higher voltage systems
  • Ensure output current does not exceed per-channel limits
  • Consider propagation delay in high-speed logic applications

Typical Circuit Usage

  • Driving relays or solenoids from logic signals
  • LED or lamp drivers with higher voltage supply
  • Level shifting from 5V logic to higher voltage domains
  • Wired-OR logic configurations
  • Signal inversion in digital circuits

How to Choose This Part

  • Use when open-collector outputs are required for voltage flexibility
  • Ideal for applications needing higher voltage switching than standard TTL
  • Choose based on required sink current capability per channel
  • Consider external resistor and load requirements in design
  • Evaluate switching speed versus load capacitance

Applications

  • Industrial control logic systems
  • Interface circuits between logic families
  • Display and indicator driving circuits
  • Relay and actuator drivers
  • General-purpose digital logic inversion

Alternative / Equivalent Products

  • SN7406
  • 74LS06
  • 74HC06 (with different logic characteristics)
  • ULN2003 (for higher current array applications)
  • CD4069 (standard inverter, non open-collector)
