9314/DM9314 Quad Latch

June 1989

9314/DM9314 Quad Latch

General Description

The ’9314 is a multifunctional 4-bit latch designed for gener­al purpose storage applications in high speed digital sys­tems. 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.

Note:

The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran­teed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
