SN74HCS393DYYR is listed in the Counter Dividers range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is DUAL 4-BIT BINARY COUNTERS. Review the specifications below when checking this part for your BOM.
The SN74HCS393DYYR is a dual 4-bit binary counter from the HCS logic family, housed in a 14-pin SOT-23-THIN package. It operates within a supply voltage range of 2 V to 6 V and supports an extended temperature range of -40°C to +125°C. The device integrates two independent counters with individual clocks and direct clear inputs, enabling divide-by-256 functionality.
Verify the specific suffix DYYR corresponds to the SOT-23-THIN package and 3000-unit reel quantity. Confirm RoHS compliance and Green status requirements against current project specifications. Ensure the operating temperature range meets environmental constraints.
Select this component when space-constrained designs require dual counters. The HCS series offers Schmitt-trigger inputs suitable for noisy environments. Verify that the 2 V to 6 V supply range aligns with the target system power rails.
This part belongs to the SN74HCS393 series, which consolidates dual 4-bit counters into small form factors. It serves as a high-density alternative to standard HC logic families, reducing overall component count in PCB layouts while maintaining CMOS performance characteristics.
SN74HC393DR
The maximum clock frequency varies by supply voltage, ranging from approximately 5 MHz at 2 V to 28 MHz at 6 V.
Each of the two 4-bit counters has an independent direct clear (CLR) input that resets the respective counter.
