SCBS024C - MARCH 1989 - REVISED NOVEMBER 1993
These 10-bit bus-interface latches feature 3-state outputsdesigned specifically for driving highly capacitive or relativelylow-impedance loads. They are particularly suitable for implementingwider buffer registers, I/O ports, bidirectional bus drivers withparity, and working registers.
The ten latches of the ´BCT29841 are transparent D-typelatches. When the latch-enable (LE) input is high, the Q outputs willfollow the data (D) inputs. When LE is taken low, the Q outputs arelatched at the levels that were set up at the D inputs.
A buffered output-enable (
) input can be used to place the nine outputs in eithera normal logic state (high or low level) or a high-impedance state.In the high-impedance state, the outputs neither load nor drive thebus lines significantly. The high-impedance state and increased driveprovide the capability to drive bus lines without need for interfaceor pullup components.
The output enable ()does not affect the internal operation of the latches. Old data canbe retained or new data can be entered while the outputs are in thehigh-impedance state.
The SN54BCT29841 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74BCT29841 is characterized for operation from 0°C to70°C.
