Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type before procurement. Confirm that the supply voltage requirements align with the 4.5 V to 5.5 V operational range specified for the AHCT series. Ensure environmental conditions fall within the -40 °C to +125 °C temperature specification. Cross-reference the manufacturer part number with authorized distributor lists to guarantee authenticity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output drive capabilities. The device is suitable for designs needing balanced propagation delays across eight channels. Consider the SO20 package dimensions for PCB layout constraints. Verify that the operating voltage remains strictly within the 4.5 V to 5.5 V limits to ensure proper functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74AHC(A)HCT245 family of octal bus transceivers. It shares functional similarities with other variants like the 74HCT245 but offers distinct input level specifications. The D suffix indicates the SO20 plastic small outline package. It is designed for general-purpose digital logic interfacing tasks requiring bidirectional data flow control.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT245PW,118 serves as a pin-compatible alternative utilizing the TSSOP20 package. Designers must verify package footprint differences when substituting between SO20 and TSSOP20 variants. Electrical characteristics remain consistent across these package options within the same logic family.
