SN74ACT08NS

Overview

The SN74ACT08NS is a quad 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the 74ACT logic series, utilizing CMOS technology for low power consumption and high noise immunity. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features a propagation delay of 10 ns and provides a low-level output current of 24 mA. The component is housed in a PDIP-14 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent 2-input AND gates within a single integrated circuit.
• Utilizes advanced CMOS technology to ensure compatibility with standard TTL inputs while maintaining low power dissipation.
• Provides robust output drive capabilities suitable for interfacing with various digital loads.

Applications

• Digital signal processing systems requiring logical conjunction operations.
• Microprocessor-based control circuits for address decoding and data gating.
• General-purpose logic applications in industrial automation equipment.

Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-14 package configuration when sourcing. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure supply voltage constraints between 4.5 V and 5.5 V are strictly maintained during system design to guarantee proper logic level performance and prevent device damage.

Selection Notes

Select this component when a quad 2-input AND function is required with ACT-series speed and power characteristics. It serves as a direct replacement for older 74LS08 devices where lower power consumption is prioritized over higher drive currents. Consider the PDIP-14 through-hole package if PCB layout constraints or existing board designs necessitate manual assembly or prototyping flexibility.

Part Context

This part is a member of the Texas Instruments 74ACT family, designed to bridge the performance gap between legacy LS logic and faster AC/HC families. It offers improved switching speeds compared to standard TTL while maintaining pinout compatibility with previous generations. The SN74ACT08NS specifically denotes the non-suffix variant packaged in a plastic dual-in-line format.
