74LVT573, 74LVTH573 Low Voltage Octal Transparent Latch with 3-STATE Outputs Features General Description Input and output interface capability to systems at The LVT573 and LVTH573 consist of eight latches with 3-STATE outputs for bus organized system applications. The latches appear transparent to the data when Latch Enable (LE) is HIGH. When LE is low, the data satisfying the input timing requirements is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in the high impedance state. 5V VCC Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH573), also available without bushold feature (74LVT573) Live insertion/extraction permitted Power Up/Down high impedance provides glitch-free bus loading Outputs source/sink -32mA/+64mA Functionally compatible with the 74 series 573 Latch-up performance exceeds 500mA ESD performance: - Human-body model > 2000V - Machine model > 200V - Charged-device model > 1000V The LVTH573 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These octal latches are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT573 and LVTH573 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.

When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D-type input changes. When LE is LOW, the latches store the information that was present on the D-type inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-STATE standard outputs are controlled by the Output Enable (OE) input. When OE is LOW, the standard outputs are in the 2-state mode. When OE is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.
