SN74AC244NG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC244NG4 is an octal buffer and line driver manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +85°C. The device utilizes a 20-pin PDIP package and is RoHS compliant. It provides unidirectional data transfer with low enable control, designed for high-speed bus applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent non-inverting buffers or drivers
• Three-state outputs allowing direct connection to bus lines without additional interface hardware
• Wide power supply operation supporting both 3.3V and 5V logic systems
• Low input capacitance and fast propagation delays suitable for high-speed digital interfaces

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers for parallel data buses
• Clock distribution and timing signal buffering
• Bidirectional bus transceivers when paired with complementary logic
• Industrial control system signal conditioning

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance as per Texas Instruments standards. Confirm the package type corresponds to the standard 20-pin PDIP format. Ensure the order quantity meets distributor requirements. Check for any recent lifecycle notices regarding obsolescence or pin-to-pin replacements within the AC series family.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring multiple buffered outputs with high drive capability in a through-hole package. It is suitable for replacing older 74LS244 designs where lower power consumption and higher speed are needed. Consider the 2V to 6V operating range for compatibility with various logic families. Evaluate board space constraints against the physical dimensions of the 20-pin DIP housing.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SNx4AC244 family of octal buffers and drivers. The AC series represents advanced CMOS technology offering faster switching speeds compared to legacy LS variants while maintaining similar pinouts. The NG4 designation specifically identifies the PDIP package variant with green (lead-free) manufacturing attributes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AC244N serves as a direct functional equivalent without the specific lead-free suffix. SN74AHC244N offers similar functionality with potentially different electrical characteristics under the AHC series. Verify pin compatibility and voltage levels before substituting with other octal buffer devices.
