20-Bit Bus-Interface D-Type Latches With 3-State Outputs

These 20-bit Latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing Buffer Registers I/O ports, bidirectional bus drivers, and working Registers
The 'ABT16841 CAN be used as two 10-bit Latches or one 20-bit latch. The 20 transparent D-type Latches provide true data at the outputs. While the latch-enable (1LE or 2LE) input is high, the Q outputs of the corresponding 10-bit latch follow the D inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs.
A buffered output-enable (1OE or 2OE) input CAN be used to place the outputs of the corresponding 10-bit latch in either a normal Logic state (high or low Logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly.
The output-enable input does not affect the internal operation of the Latches Old data CAN be retained or new data CAN be entered while the outputs are in the high-impedance state.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT16841 is characterized for operation over the full military temperature range of -55C to 125C. The SN74ABT16841 is characterized for operation from -40C to 85C.
