Description

This is Octal Transparent Latches. UT54ACS373, UT54ACTS373 Radiation-Hardened Octal Transparent Latches with Three-State Outputs FEATURES 8 latches in a single package Three-state bus-driving true outputs Full parallel access for loading radiation-hardened CMOS - Latchup immune High speed Low power consumption Single 5 volt supply Available QML Q or V processes Flexible package - 20-pin DIP - 20-lead flatpack DESCRIPTION The UT54ACS373 and the UT54ACTS373 are 8-bit latches with three-state outputs designed for driving highly capacitive or relatively low-impedance loads. The device is suitable for buffer registers, I, O ports, and bidirectional bus drivers. The eight latches are transparent D latches. While the enable (C) is high the Q outputs will follow the data (D) inputs. When the enable is taken low, the Q outputs will be latched at the levels that were set up at the D inputs. An output-control input (OC) places the eight outputs in either a normal logic state (high or low logic levels) or a high-.
