Overview
The 74LV4094D, produced by Nexperia USA Inc., is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. This device is part of the low-voltage Si-gate CMOS family and is pin and functionally compatible with the 74HC4094 and 74HCT4094. It features separate clocks for both the shift and storage registers, making it versatile for various applications.
The 74LV4094D operates over a wide voltage range from 1.0 V to 3.6 V, making it suitable for a variety of electronic designs. It includes a serial input (D) and two serial outputs (QS1 and QS2) to facilitate cascading, and the data is shifted on the LOW-to-HIGH transitions of the CP input.
