PDTC143ZT Digital Transistors

The HEF4053B is a triple single-pole double-throw analog switch (3x SPDT) suitable for use in analog or digital 2:1 multiplexer /demultiplexer applications. Each switch features a digital select input (Sn), two independent inputs/outputs (Y0 and Y1) and a common input/output (Z). A digital enable input (E) is common to all switches. When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VDD.

The ’HC597 is high-speed silicon gate CMOS devices that are pin compatible with the LSTTL 597 devices. Each device consists of an 8-flip-flop input register and an 8-bit parallel-in/serial-in, serial-out shift register. Each register is controlled by its own clock. BRAND - NEXPERIA PACKAGE - SOIC 16
