SN74HCT08DBR

Inverter Gates Overview

The SN74HCT08DBR is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs with low input current. The device provides ±4mA output drive at 5V and consumes a maximum supply current of 20µA. Propagation delay typically ranges from 13ns to 30ns depending on voltage and temperature. It is housed in a 14-pin SSOP package and supports an operating temperature range of -40°C to 85°C.

Inverter Gates Feature Summary

• Contains four independent 2-input AND gates performing the Boolean function Y = A • B
• Inputs are compatible with standard TTL voltage levels
• Outputs can drive up to ten LSTTL loads
• Low power consumption with maximum ICC of 20µA

Inverter Gates Applications

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-14 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the supplier provides valid traceability documentation for production-grade components.

Inverter Gates Selection Notes

Select this component when TTL-compatible CMOS logic is required for 5V systems. The HCT series ensures compatibility with existing TTL designs while offering lower power consumption than bipolar alternatives. Verify that the 14-pin SSOP package fits the available PCB footprint and thermal requirements.

Inverter Gates Part Context

This part belongs to the SN74HCT08 family of quadruple 2-input AND gates. It is designed as a CMOS alternative to bipolar logic families, providing similar functionality with improved power efficiency. The DBR suffix indicates surface-mount packaging suitable for automated assembly processes.

Inverter Gates FAQ

What is the recommended handling procedure for unused inputs?

All unused inputs must be connected to VCC or GND to prevent undefined operational states caused by floating voltages.

How should bypass capacitors be placed?

A 0.1-μF capacitor is recommended for each VCC terminal and should be installed as close to the power terminal as possible to prevent power disturbances.
