SN74ALS842DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS842DW is a 10-bit bus-interface D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from 0°C to 70°C. The device features inverting data inputs and utilizes a buffered output-enable input for high-impedance control. Propagation delays from the data input to the output range from 4 ns to 18 ns, while latch enable propagation ranges from 6 ns to 27 ns depending on conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features ten transparent D-type latches with inverting data inputs designed for bus applications
• Provides 3-state buffer-type outputs capable of driving highly capacitive or low-impedance loads directly
• Includes a buffered output-enable input that places outputs in a high-impedance state without affecting internal latch operation

Buffers, Drivers, Receivers, Transceivers Applications

• Implementing buffer registers in digital systems
• Configuring I/O ports for microprocessor interfaces
• Serving as bidirectional bus drivers
• Functioning as working registers in memory architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package option addendum to confirm the exact physical package type and material specifications. Ensure the component meets RoHS compliance requirements relevant to your manufacturing process. Confirm the active production status and check for any product change notifications prior to finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 10-bit parallel data storage with tri-state bus capabilities. The inverting logic function distinguishes it from non-inverting variants like the SN74ALS841. Consider the ALS series characteristics for moderate speed and power consumption balance compared to standard TTL or faster AS series options.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments SN74ALS family of advanced small-scale integration logic devices. It shares the same pinout and general functionality as the SN74ALS841 and SN74AS841A, differing primarily in the inversion of its data inputs. The DW package denotes a plastic small-outline configuration suitable for surface-mount assembly.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ALS841DW serves as a functional substitute if inverting data inputs are not required.
