74393 Dual 4-bit Binary Ripple Counter IC (74393 IC)

From the shop's description

74HC393 Dual 4-bit Binary Ripple Counter IC (74393 IC) 74HC393 is a 14 Pin Dual 4-bit Binary Ripple Counter IC having 2V to 6V Operating Voltage range and 50 Mhz Clock Frequency. Each counter features a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of nCP. A HIGH on nMR clears the counter stages and forces the outputs LOW, independent of the state of nCP. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Specifications:- Package Type: DIP Voltage Rating: 2 to 6V Temperature Rating: -40 to 125 Deg C Number of Pins: 14 Frequency: 50MHz Propagation Delay: 13ns Datasheet:- 74HC393 IC Datasheet
