Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

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 a high impedance state. ■ ■ ■ ■ ■ ■ 5V VCC Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH373), also available without bushold feature (74LVT373) Live insertion/extraction permitted Power Up/Down high impedance provides glitch-free bus loading Outputs source/sink –32 mA/+64 mA Functionally compatible with the 74 series 373 ESD performance: – Human-body model > 2000V – Machine model > 200V – Charged-device model > 1000V The LVTH373 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 LVT373 and LVTH373 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining 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 input changes. When LE is LOW, the latches store the information that was present on the D 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. ©1999 Fairchild Semiconductor Corporation 74LVT373, 74LVTH373 Rev. 1.5.0 Outputs LE OE Dn On X H X Z H L L L H L H H L L X O0 H = HIGH Voltage Level L = LOW Voltage Level Z = High Impedance X = Immaterial O0 = Previous O0 before HIGH-to-LOW transition of Latch Enable www.fairchildsemi.com 2 74LVT373, 74LVTH373 — Low Voltage Octal Transparent Latch with 3-STATE Outputs Connection Diagram Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. ©1999 Fairchild Semiconductor Corporation 74LVT373, 74LVTH373 Rev. 1.5.0 www.fairchildsemi.com 3 74LVT373, 74LVTH373 — Low Voltage Octal Transparent Latch with 3-STATE Outputs Logic Diagram Stresses exceeding the absolute maximum ratings may damage the device.
