9314 DM9314 Quad Latch
General Description
The ’9314 is a multifunctional 4-bit latch designed for gener-
al purpose storage applications in high speed digital sys-
tems All outputs have active pull-up circuitry to provide high
capacitance drive and to provide low impedance in both
logic states for good noise immunity
