SN74AC11D

Overview

The SN74AC11D is a triple 3-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features low static power consumption with a maximum quiescent current of 2µA. The device provides symmetrical output drive capabilities of ±24mA at 5V. Propagation delay is typically 8ns at 5V with a 50pF load. It is housed in a 14-TSSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Triple 3-input AND logic function
• Wide 2V to 6V supply voltage operation
• High noise immunity and low static power consumption

Applications

• Parallel data synchronization circuits
• Memory address decoding systems
• Control logic for digital signal processing

Procurement Notes

Verify the specific suffix 'D' corresponds to the 14-TSSOP package configuration required for your design. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure input voltage levels remain within specified limits relative to the selected supply voltage to prevent latch-up or damage during operation.

Selection Notes

Select this component when a wide supply voltage range including 3.3V and 5V systems is required. The AC series offers faster switching speeds compared to standard TTL or LS families while maintaining low power dissipation. Verify that the TSSOP footprint matches the PCB layout constraints and thermal requirements of the target application environment.

Part Context

This part belongs to the SN74AC11 family of high-speed CMOS logic gates. It serves as a direct functional replacement for older bipolar technologies but with significantly reduced power consumption. The device is designed for general-purpose digital applications requiring reliable AND logic operations across varying industrial and commercial temperature ranges.
