Descriptions
IC S-R LATCH SGL TRI-ST 24SOIC:Heisener Electronics
The SN74BCT29843 features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers. The nine latches are transparent D-type latches. When the latch-enable (LE) input is high, the Q outputs are complementary to the noninverting data (D) inputs. A buffered output-enable () input can be used to place the nine outputs in either a normal logic state (high or low level) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without need for interface or pull-up components. The output enable () does not affect the internal operation of the flip-flops. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The SN74BCT29843 is characterized for operation from 0°C to 70°C.:Texas Instruments
