Overview
The SN74ALS1005DR is a hex inverting buffer manufactured by Texas Instruments, featuring open-collector outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a low-level input logic voltage of 0.8 V. The device provides a low-level output current capability of 24 mA. It is housed in a 14-SOIC package and functions across an operating temperature range of 0°C to 70°C.
Feature Summary
- Hex inverting buffer configuration with six independent channels
- Open-collector output structure for flexible interfacing
- High low-level sink current capability
Applications
- Bus-oriented systems requiring line driving
- Memory address decoding circuits
- General-purpose digital signal inversion
Procurement Notes
Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the open-collector nature of the outputs aligns with the target circuit design requirements. Ensure the 4.5V to 5.5V supply voltage range matches the system power rails. Check for any end-of-life notifications or alternative component recommendations from the manufacturer.
Selection Notes
Select this component when a hex inverter with high-current sinking capability is required. The open-collector outputs allow for wired-AND connections and level shifting. Consider the SOIC package size for PCB layout constraints. Verify that the 70°C maximum operating temperature is sufficient for the intended environment.
Part Context
This part belongs to the SN74ALS series of advanced low-power Schottky logic devices. These components are designed for high-speed applications while maintaining lower power consumption compared to standard TTL. The SN74ALS1005 specifically provides buffering and inversion functions suitable for digital logic interfaces.
FAQ
What is the maximum low-level output current?
The device can sink up to 24 mA in the low state.
Does this IC have internal pull-up resistors?
No, it features open-collector outputs which require external pull-up resistors for proper operation.
