It counts on the positive edge of the clock, with a maximum count rate of 35 MHz, and supports both up and down counting directions via a dedicated control input. ## Second-source consideration against CY74FCT191ATSOC A functional peer is the CY74FCT191ATSOC from the 74FCT family, which is also a synchronous up/down counter but implements a binary (not BCD) count sequence. The two are not pin-compatible — the CY74FCT191ATSOC uses a different package — so a board spin is required to substitute.","metaTitle":"CD74HC190PW 74HC BCD Up/Down Counter, 35 MHz, 16-TSSOP","metaDescription":"Texas Instruments CD74HC190PW synchronous BCD up/down counter, 35 MHz count rate, 2-6 V supply, -55 to 125°C.
