Product Overview: SN74LV595APW

The SN74LV595APW is a high-performance, 8-bit shift registers with output latches from Texas Instruments, designed to provide efficient serial-to-parallel data conversion. This integrated circuit (IC) is part of the LV family, which signifies that it operates at a low voltage range, making it suitable for battery-powered and portable applications where power consumption is critical.

The device features an 8-bit serial-in, parallel-out shift register that enables the system to expand the number of I/O lines. The SN74LV595APW is particularly useful in applications where pins are limited, and there is a need to drive multiple outputs, such as LEDs, displays, or other digital devices.

Key Features:

• 2-V to 5.5-V V<sub>CC operation.
• Shift register with direct clear.
• 8-bit serial input to parallel output functionality.
• Output drive capability: 15 LSTTL loads.
• Low power consumption with typical t<sub>pd of 13 ns.
• ±4-mA output drive at 5 V.
• Low input current of 1 µA max.

The SN74LV595APW is designed with an edge-triggered clock input (SHCP), a serial data input (SER), and an output enable input (OE). The device also has a clear function (SRCLR) which can be used to clear the internal registers. The output enable function allows the user to place the eight outputs in either a high-impedance state or an active state, thus providing additional flexibility in controlling the connected loads.

Packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package), the SN74LV595APW offers a compact solution for space-constrained applications. The product is characterized for operation from -40°C to 85°C, making it reliable in a wide range of environments.

Whether used in microprocessor extension, portable systems, or for driving LEDs, the SN74LV595APW from Texas Instruments is an excellent choice for designers looking to optimize their system's performance with low-power, high-speed serial-to-parallel data conversion.
