Counter Dividers Procurement Notes

Verify the specific TSSOP-16 package configuration matches the design requirements. Confirm that the operating temperature range aligns with the intended environmental conditions. Ensure that the supply voltage constraints are strictly adhered to during system integration. Check for any specific handling precautions related to the CMOS technology used in fabrication.

Counter Dividers Selection Notes

Select this component when a high-speed, low-power synchronous counter is required. The 74AC163TTR is suitable for applications demanding fast clock frequencies up to 200MHz. Consider its compatibility with standard 74 series logic functions if pin compatibility is a priority. Evaluate the power consumption benefits compared to older logic families for battery-operated devices.

Counter Dividers Part Context

This part belongs to the 74AC family of advanced CMOS logic devices from STMicroelectronics. It serves as a direct functional replacement for the standard 74LS163 but with significantly improved speed and lower power consumption. The TTR suffix indicates it is supplied in a tape and reel format, suitable for automated surface-mount assembly processes.

Counter Dividers Replacement Considerations

Direct substitutes include other manufacturers' 74AC163 variants in TSSOP-16 packages. Verify electrical characteristics such as propagation delay and supply current when cross-referencing with alternative brands. Ensure pinout compatibility remains identical to avoid PCB redesign.
