74LVT16373: Low Voltage 16-Bit Transparent Latch with 3-STATE Outputs

The LVT16373 and LVTH16373 contain sixteen non-inverting latches with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. The flip-flops appear transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE#) is LOW. When OE# is HIGH, the outputs are in a high impedance state.     The LVTH16373 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.     These latches are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT16373 and LVTH16373 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
