U74HC595AG-S16-R

Description

74HC595 8-bit shift register with latch, SOIC-16 — UTC.

The U74HC595AG-S16-R is a high-speed CMOS 8-bit serial-in, serial or parallel-out shift register featuring an output latch and 3-state (tri-state) outputs . It is manufactured by Unisonic Technologies (UTC). This integrated circuit (IC) is widely implemented to expand the available digital output pins on microcontrollers. [ 1 , 2 , 3 , 4 , 5 ] Part Number Breakdown U74HC : High-speed CMOS logic family. 595 : 8-bit shift register with storage register configuration. A : Specific design revision or modification variant.

Output Current Capability : Up to \(35\text{mA}\) per pin. Propagation Delay : \(14\text{ns}\) at \(6\text{V}\) with a \(50\text{pF}\) load. Power Dissipation (\(P_{d}\)) : Maximum \(500\text{mW}\). Operating Temperature Range : \(-40^{\circ }\text{C}\) to \(+125^{\circ }\text{C}\). [ 1 ] Functionality The IC accepts data serially through the serial input pin (SER). The internal shift register advances data on the low-to-high transition of the shift clock (SRCLK). Data transfers to the storage register on a low-to-high transition of the latch clock (RCLK). The 3-state parallel outputs (\(Q_{0}\)–\(Q_{7}\)) can drive high-current loads directly, such a
