54ACTQ841 Quiet Series 10-Bit Transparent Latch with TRI-STATE Outputs
General Description
The ’ACTQ841 bus interface latch is designed to eliminate the extra packages required to buffer existing latches and provide extra data width for wider address/data paths or buses carrying parity. The ’841 is a 10-bit transparent latch, a 10-bit version of the ’373. The ’ACTQ841 utilizes NSC Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance, FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.
Features
n Guaranteed simultaneous switching noise level and dynamic threshold performance n Inputs and outputs on opposite sides of package allow easy interface with microprocessors n Improved latch-up immunity n Outputs source/sink 24 mA n ’ACTQ841 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) 5962-92200
