The 74HCS165 is an 8-bit serial or parallel-in/serial-o
ut 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 PLis 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 CEwill 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.
All inputs are Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
Features and benefits
Wide supply voltage range from 2.0 V to 6.0 V
Schmitt-trigger inputs
Low power consumption
Typical supply current (ICC) of 100 nA
Typical input leakage current (II) of ±10 nA
±7.8 mA output drive at 6 V
8-bit serial input and 8-bit serial or parallel output
Storage register with 3-state outputs
Shift register with direct clear
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
Complies with JEDEC standards:
JESD7A (2.0 V to 6.0 V)
Applications
Parallel-to-serial data conversion
Remote control holding register
Output expansion
LED matrix control
7-segment display control
8-bit data storage
