Toshiba 74HC595D 8-Bit High Speed Shift Register/Latch SOIC 16-Pin Surface Mount 2-6V 125°C 74HC595D

Toshiba 74HC595D is a high speed 8-bit shift register/latch using silicon gate C2MOS technology, offered in a SOIC 16-pin surface mount package. Operating with a supply voltage between 2 V and 6 V, and capable of functioning in environments up to 125°C, it delivers high speed logic performance equivalent to LSTTL devices but with the CMOS benefit of low power dissipation.

The device integrates a static shift register which feeds into a storage register. Data shift occurs on the positive transition of the shift clock (SCK), and the output register loads the shifted contents on the positive transition of the register clock (RCK). This mechanism allows outputs to remain stable during shifting operations, while the three-state parallel outputs can be connected directly to an 8-bit bus, facilitating serial-to-parallel data conversion.

With a maximum frequency (fMAX) typically at 55 MHz at 5 V and an ICC maximum of 4.0 μA at room temperature, the 74HC595D is optimized for high-speed, low-power applications including data receivers, multiplexers, and other logic circuits.

Its compact physical dimensions of 10.2 mm length, 3.9 mm width, and 1.75 mm height enable space-efficient PCB layouts in electronic and industrial equipment. The product does not carry automotive qualification or additional standards approvals but is widely applicable in industrial electronics and digital logic designs.

Features such as balanced propagation delays (tPLH ≈ tPHL) and static input protection against ESD and transient voltages enhance reliability in demanding environments. Fabricated with C2MOS silicon gate technology for high speed and power efficiency.

Compatible with 2.0 to 6.0 V operating voltage ranges for flexible design integration. High-speed operation with fMAX of 55 MHz at 5 V supply voltage. Low current consumption ICC max 4.0 μA at 25°C for energy-saving applications.

Three-state parallel outputs allow direct bus driving and improved control. Stable outputs maintained during shifts by independent register clocking. Compact 16-pin SOIC package supports surface mount technology. Wide operating temperature up to 125°C for industrial applications.

Balanced propagation delays improve timing precision in high-speed circuits. Robust input protection circuits shield against static and transient voltages.

This Toshiba 74HC595D shift register/latch is ideal for industrial electronics, laboratory equipment, and digital systems requiring serial-to-parallel data shifts with high speed and low power requirements. It supports integration in automation, control systems, signal processing, and embedded electronic devices.
