Overview
The SN74LV595AIPWREP, produced by Texas Instruments, is an 8-bit serial-in, parallel-out shift register with 3-state output registers. This device is part of the SN74LV595A series and is specifically packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package). It is designed to operate over a wide voltage range of 2 V to 5.5 V, making it versatile for various applications.
The device includes a shift register and a storage register, both of which are clocked by separate positive-edge triggered clocks (SRCLK and RCLK). It also features a direct overriding clear input (SRCLR) and supports mixed-mode voltage operation on all ports. The SN74LV595AIPWREP is qualified for automotive applications and offers customer-specific configuration control along with major-change approval.
