20-BIT BUS-INTERFACE D-TYPE LATCHES

D Members of the Texas Instruments WidebusE Family D Output Ports Have Equivalent 25-Ω Series Resistors, So No External Resistors Are Required D Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 5 V, TA = 25°C D High-Impedance State During Power Up and Power Down D Ioff and Power-Up 3-State Support Hot Insertion D Distributed VCC and GND Pins Minimize High-Speed Switching Noise D Flow-Through Architecture Optimizes PCB Layout D Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17 description/ordering information These 20-bit transparent D-type latches feature noninverting 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 ’ABT162841 devices can be used as two 10-bit latches or one 20-bit latch. While the latch-enable (1LE or 2LE) input is high, the Q outputs of the corresponding 10-bit latch follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs.
