74HC165D

74HC165 8-bit parallel-in/serial out shift register Draft datasheet, Rev. 1.0 Aug 08, 2024 1.General Description The 74HC165is an 8-bit serial or parallel-in/serial-out shift register. The device features a serial data input (DS), eight parallel data inputs (D0 to D7) and two complementary serial outputs (Q7 and Q7). When the parallel load input (PL) is LOW the data from D0 to D7 is loaded into the shift register asynchronously. When PL is HIGH data enters the register serially at DS. When the clock enable input (CE) is LOW data is shifted on the LOW-to-HIGH transitions of the CP input. A HIGH on CE will disable the CP input. Inputs include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2.Features and Benefits  Wide supply voltage range from 2.0 V to 6.0 V  High noise immunity  CMOS low power dissipation  Asynchronous 8-bit parallel load  Synchronous serial input  Latch-up performance exceeds 250 mA  Complies with JEDEC standard: • JESD8C(2.7 V to 3.6 V) • JESD7A(2.0 V to 6.0 V)  ESD protection: • HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 3500 V • CDM ANSI/ESDA/JEDEC JS-002 Class C3 exceeds 2000 V  Multiple package options  Specified from -40 °C to +85 °C and from -40 °C to +125 °C Rev. 1.0 – Aug 08, 2024 1 74HC165 8-bit parallel-in/serial out shift register Draft datasheet, Rev. 1.0 Aug 08, 2024 3.Ordering Information Table 1.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Table 4.
