SN74ALVCH16344DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16344DLR is a 1-bit to 4-bit address driver with 3-state outputs, designed for 1.65-V to 3.6-V VCC operation. It contains four separate drivers, each converting one input to four outputs. The device features active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors. It operates within an ambient temperature range of -40°C to 85°C and is housed in a 56-pin SSOP (DL) package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Active bus-hold circuitry maintains unused or undriven inputs at a valid logic state without requiring external resistors.
• Latch-up performance exceeds 250 mA per JESD 17 standards.
• ESD protection exceeds 2000-V human-body model and 200-V machine model specifications.

Buffers, Drivers, Receivers, Transceivers Applications

• Addressing four separate memory locations using a single address line
• Bus hold applications eliminating external pullup/pulldown resistors

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity as this part is obsolete. Confirm that the DL suffix corresponds to the SSOP package type. Ensure the replacement meets the required voltage and temperature specifications if sourcing from secondary markets.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring a single address signal to drive multiple memory banks simultaneously. Verify compatibility with the target supply voltage range between 1.65 V and 3.6 V. Consider the 56-pin SSOP footprint constraints during PCB layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family of logic components. It functions specifically as an address driver rather than a standard buffer or transceiver. The DL suffix indicates the plastic small-outline package variant manufactured by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the bus-hold feature function?

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state, removing the requirement for external pullup or pulldown resistors.

What is the purpose of tying OE to VCC during power up?

Tying the Output Enable (OE) pin to VCC through a pullup resistor ensures a high-impedance state during power up or power down conditions.
