SN74AUCH244RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUCH244RGYR is an octal buffer/driver from the AUCH series, organized as two independent 4-bit line drivers with separate output-enable inputs. It operates within a supply voltage range of 0.8 V to 2.7 V and features a maximum propagation delay of 1.9 ns at 1.8 V. The device provides ±8 mA output drive current at 1.8 V and includes active bus-hold circuitry on data inputs. It supports partial-power-down mode via Ioff circuitry and offers ESD protection exceeding 2000 V per the human-body model.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Active bus-hold circuitry maintains valid logic states for unused or undriven inputs without requiring external resistors
Ioff circuitry disables outputs during power-down to prevent damaging backflow currents in mixed-mode systems
High electrostatic discharge protection ratings across human-body, machine, and charged-device models

Buffers, Drivers, Receivers, Transceivers Applications

Partial-power-down applications requiring controlled high-impedance states
Mixed-mode signal operation between low-voltage cores and 3.6-V tolerant I/Os
Octal bus buffering with independent enable control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix RGY corresponds to the 20-pin VQFN package with tape-and-reel packaging. Confirm that the component meets RoHS compliance standards and check the moisture sensitivity level rating prior to surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring sub-1-V operation combined with 3.6-V input tolerance. The integrated bus-hold feature simplifies board layout by eliminating the need for discrete pull-up or pull-down components on data lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74AUCH family, which is optimized for ultra-low-voltage digital logic applications. The device serves as a non-inverting buffer/driver suitable for high-speed data transmission in portable and battery-powered electronic equipment.
