1 / 13 page SN74LVCH16373A 16BIT TRANSPARENT DTYPE LATCH WITH 3STATE OUTPUTS SCAS568L − MARCH 1996 − REVISED SEPTEMBER 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Member of the Texas Instruments Widebus Family D Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C D Typical VOHV (Output VOH Undershoot) >2 V at VCC = 3.3 V, TA = 25°C D Ioff Supports Partial-Power-Down Mode Operation D Supports Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC) D Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors D Latch-Up Performance Exceeds 250 mA Per JESD 17 D ESD Protection Exceeds JESD 22 − 2000-V Human-Body Model (A114-A) − 200-V Machine Model (A115-A) description/ordering information This 16-bit transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation. The SN74LVCH16373A is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as two 8-bit latches or one 16-bit latch. When the latch-enable (LE) input is high, the Q outputs follow the data (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 (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the 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 interface or pullup components.
