Key Features
- 8-bit serial-in, parallel-out shift register with two serial data inputs (DSA and DSB) and eight parallel data outputs (Q0 to Q7).
- Data is shifted on the LOW-to-HIGH transitions of the clock (CP) input.
- Asynchronous master reset (MR) input clears the register and forces all outputs LOW.
- Inputs include clamp diodes for interfacing with voltages in excess of VCC.
- CMOS low power dissipation and high noise immunity.
- Complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V).
- Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
- ESD protection: HBM (ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V) and CDM (ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V).
- Multiple package options, including DHVQFN package with Side-Wettable Flanks for Automatic Optical Inspection (AOI) of solder joints.
