MC74HCT163ADR2 is listed in the Counter Dividers range at ChipApex. The manufacturer field lists onsemi. Its product description is BINARY COUNTER, HCT SERIES, SYNC. Review the specifications below when checking this part for your BOM.
The MC74HCT163ADR2 is a synchronous 4-bit binary counter from the HCT logic series, manufactured by onsemi. It features synchronous preset capability and operates within a supply voltage range of 4.5 V to 5.5 V. The device is housed in a 16-pin SOIC package with surface mount installation. It provides high noise immunity and low input current characteristics typical of CMOS technology, ensuring compatibility with standard TTL outputs when pull-up resistors are utilized.
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix 'ADR2' indicates the SOIC-16 tape and reel packaging configuration. Ensure compliance with RoHS directives if required for your assembly process. Check for end-of-life status updates as availability may vary.
Select this component when synchronous reset and preset operations are required over asynchronous alternatives. The HCT series ensures direct interface compatibility with 5V TTL logic levels. Consider the SOIC-16 package constraints for PCB layout and thermal management requirements during design integration.
This part belongs to the MC74HC/HCT163 family of presettable counters. It shares pinout compatibility with LS163 devices but offers improved speed and lower power consumption due to advanced CMOS fabrication processes. The family supports various package options including DIP and SOIC formats for diverse mounting needs.
MC74HC163ADG: HC series variant with wider voltage range. MC74HCT163AD: Alternative HCT package option. SN74HCT163N: Texas Instruments equivalent. Verify logic level compatibility and package dimensions before substitution.
