It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while main- taining the CMOS low power dissipation. This 8-bit D-type latch is controlled by a Latch Enable input (LE) and an Output Enable input (OE). When the OE input is HIGH, the eight outputs are in a high impedance state. Protection circuits ensure that 0V to 7V can be applied to the input and output(1) pins without regard to the supply voltage. This device can be used to interface 3V to 5V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mis- matched supply and input voltages. Note: 1. Outputs in OFF-State 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.
