SN74ACT244NSRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT244NSRG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74ACT advanced CMOS logic series. It features eight non-inverting outputs with three-state capability, organized into two independent four-bit sections controlled by separate output enable (OE) inputs. The device operates within a supply voltage range of 4.5V to 5.5V and accepts TTL-compatible input voltages up to 5.5V. It provides high-speed performance with a maximum propagation delay of 9.5ns at 5V and supports output drive currents of ±24mA. The component is housed in a 20-pin SOIC package and is rated for operation from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the package type corresponds to the 20-pin Small Outline Integrated Circuit (SOIC) variant. Ensure the ordering part number matches the exact manufacturer designation to avoid discrepancies in lead times or packaging quantities.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density octal buffering with three-state control. It is suitable for interfacing between different logic families due to its TTL-compatible inputs. Consider the 9.5ns propagation delay and ±24mA drive strength for signal integrity requirements. Verify that the 4.5V to 5.5V operating voltage aligns with the system's power supply rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SNx4ACT244 family of octal buffers and drivers. The 'ACT' designation signifies Advanced CMOS technology, offering faster switching speeds than standard AC logic while maintaining lower power consumption. The 'NSR' suffix typically denotes the 20-pin SOIC package in tape-and-reel format, though the 'G4' suffix confirms environmental compliance.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ACT244NSR is a direct functional equivalent without the G4 suffix. SN74ACT244PWR serves as an alternative in TSSOP-20 packaging. SN74HCT244 variants offer similar functionality but with HCT input thresholds.
