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 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. ■ Input and output interface capability to systems at 5V VCC ■ Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH16373), also available without bushold feature (74LVT16373) ■ Live insertion/extraction permitted ■ Power Up/Power Down high impedance provides glitch-free bus loading ■ Outputs source/sink 32 mA/64 mA ■ Functionally compatible with the 74 series 16373 ■ Latch-up performance exceeds 500 mA ■ ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000V ■ Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary) Ordering Code: Order Number Package Number 74LVT16373GX (Note 1) BGA54A (Preliminary) Package Description 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide [TAPE and REEL] 74LVT16373MEA (Note 2) MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide 74LVT16373MTD (Note 2) MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide 74LVTH16373GX (Note 1) BGA54A (Preliminary) 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide [TAPE and REEL] 74LVTH16373MEA (Note 2) MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide 74LVTH16373MTD (Note 2) MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide Note 1: BGA package available in Tape and Reel only.

The device is byte controlled with each byte functioning identically, but independent of the other. Control pins can be shorted together to obtain full 16-bit operation. The following description applies to each byte. When the Latch Enable (LEn) input is HIGH, data on the Dn enters the latches. In this condition the latches are transparent, i.e, a latch output will change states each time its D input changes. When LEn is LOW, the latches store information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LEn. The 3-STATE standard outputs are controlled by the Output Enable (OEn) input. When OEn is LOW, the standard outputs are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.
