It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The signal level applied to the D INPUT is transferred to the Q OUTPUT during the positive going transition of the CK pulse. CLR and PR are independent of the CK and are accomplished by setting the appropriate input LOW. Protection circuits ensure that 0V to 7V can be applied to the input pins without regard to the supply voltage and to the output pins with VCC = 0V. These circuits prevent device destruction due to mismatched supply and input/ output voltages. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup. Ordering Information Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering number. Pb-Free package per JEDEC J-STD-020B. Note: 1. Device available in Tape and Reel only.
