Presettable Synchronous 4-bit Binary Up/down Counter

The 74HC/HCT193 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT193 are 4-bit synchronous binary up/down Counters Separate up/down Clocks CPU and CPD respectively, simplify operation. The outputs change state synchronously with the LOW-to-HIGH transition of either Clock input. If the CPU Clock is pulsed while CPD is held HIGH, the device will count up. If the CPD Clock is pulsed while CPU is held HIGH, the device will count down. Only one Clock input CAN be held HIGH at any time, or erroneous operation will result. The device CAN be cleared at any time by the asynchronous master reset input (MR); it may also be loaded in parallel by activating the asynchronous parallel load input (PL). By NXP Semiconductors
