74HCT08DTR2G

Overview

The onsemi 74HCT08DTR2G is a quad 2-input AND gate utilizing high-performance silicon-gate CMOS technology. It operates within a DC supply voltage range of 4.5 V to 5.5 V and supports an extended operating temperature range from -55°C to +125°C. The device features TTL-compatible inputs, allowing direct interfacing with CMOS, NMOS, and TTL logic families. It provides an output drive capability equivalent to 10 LSTTL loads and includes protection circuitry against electrostatic discharge (ESD) exceeding 2000 V per the Human Body Model. The component is housed in a TSSOP-14 surface-mount package.

Feature Summary

• High-performance silicon-gate CMOS construction ensures low input current and high noise immunity characteristics typical of CMOS devices.
• TTL/NMOS-compatible input levels allow direct interface with standard logic families without additional level shifting components.
• Robust ESD protection capabilities safeguard the internal circuitry against damage from static voltages up to specified thresholds.

Applications

• Digital logic signal combination and processing
• Pulse gating and clock synchronization circuits
• Microcontroller peripheral control interfaces

Procurement Notes

Verify the specific suffix 'DTR2G' corresponds to the TSSOP-14 package configuration rather than the SOIC-14 variant. Confirm RoHS compliance status as the datasheet indicates this package is inherently lead-free. Ensure the ordering quantity aligns with tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when a quad 2-input AND function is required with strict TTL compatibility constraints. The wide operating temperature range makes it suitable for industrial environments. Verify that the 4.5 V to 5.5 V supply voltage requirement matches the system power rails before finalizing the design integration.

Part Context

This device belongs to the 74HCT series of high-speed CMOS logic integrated circuits manufactured by onsemi. It serves as a functional replacement for legacy LS08 designs while offering improved power efficiency and noise immunity. The pinout remains identical to standard LS08 packages to facilitate drop-in upgrades in existing hardware architectures.

Replacement Considerations

Public confirmed substitute part numbers include MC74HCT08ADR2G and MM74HCT08M.
