SN74ALS191ANSRE4 Product Details

SN74ALS191ANSRE4 Overview


This is a device supplied in the 16-SOIC (0.209, 5.30mm Width) package. There are 16terminations used for configuring it. The supply voltage of 5V permits it to operate with full flexibility. There are 1 terminations on the device. There are a total of 16 pins in all components. As a result, it is packaged as Tape & Reel (TR). As part of the circuit, there are 16pins used to connect other components. It is mounted in the direction of [0]. The ALSfamily is derived from it. Having been designed as a member of the 74ALSseries, it is well suited for use in a wide range of applications. Binary Counteris selected as the logic type. In this case, the operating temperature should be set to 0°C~70°C. Having a mounting type of [0], it is suitable for installation. By providing the supply voltage of [0], it is capable of operating more reliably. The array stores 4bits in each element. These electronic devices have many important features, and TCO OUTPUTis one of them. There are more related parts under the 74ALS191base part number. It is packed with [0]. In this case, there is 5V voltage coming from the voltage source. The device operates on a supply voltage of [0]. With a frequency of [0], it operates.
