Flip Flops datasheet and documents for SN74ALS29821DWR

SN74ALS29821DWR

Flip Flops Overview

The SN74ALS29821DWR is a 10-bit edge-triggered D-type flip-flop featuring 3-state outputs, manufactured by Texas Instruments in the ALS logic series. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 75 MHz. The device provides high drive capability with a low-level output current of 48 mA and a high-level output current of -24 mA. Packaged in a surface-mount SOIC format, it is designed for driving highly capacitive or low-impedance loads.

Flip Flops Feature Summary

Features 3-state outputs specifically designed for driving highly capacitive or relatively low-impedance loads.
Includes undershoot-protection circuitry on the outputs to ensure signal integrity.
Utilizes buffered control inputs to reduce DC loading effects on the system bus.

Flip Flops Applications

Implementing wider buffer registers for expanded data paths.
Serving as I/O ports in digital systems.
Functioning as bidirectional bus drivers with parity capabilities.
Operating as working registers in high-speed logic circuits.

Flip Flops Procurement Notes

Verify that the specific ordering suffix corresponds to the SOIC surface-mount package variant. Confirm the supply voltage requirements align with standard 5 V logic systems, as the device specifies a narrow operating range between 4.75 V and 5.25 V. Ensure compatibility with bipolar input technology when integrating into existing ALS family designs.

Flip Flops Selection Notes

Select this component when a 10-bit width is required for address or data buses. It is suitable for applications needing high-speed performance up to 75 MHz. Consider its 3-state output capability for multiplexed bus architectures. Verify that the power-up high-impedance state requirement is met for safe bus initialization.

Flip Flops Part Context

This part belongs to the Texas Instruments ALS (Advanced Low-Power Schottky) series of logic devices. It is functionally equivalent to the AMD AM29821. The device is categorized under trigger, latch, and register components, specifically designed for bus interface applications requiring high drive strength and speed.
