74HC190 Presettable synchronous BCD decade up/down counter

74HC190 Description

INTEGRATED CIRCUITS DATA SHEET For a complete data sheet, please also download: * The IC06 74HC/HCT/HCU/HCMOS Logic Family Specifications The 74HC/HCT190 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).

74HC190 Features

* Synchronous reversible counting
* Asynchronous parallel load
* Count enable control for synchronous expansion
* Single up/down control input
* Output capability: standard

74HC190 Applications

* Fig.6 shows a method of causing state changes to occur simultaneously in all stages. The RC outputs propagate the carry/borrow signals in ripple fashion and all clock inputs are driven in parallel. In this configuration the duration of the clock LOW state must be long enough to allow the negative-g
