74LVX4245MTCX

Translators, Level Shifters Overview

The onsemi 74LVX4245MTCX is an 8-bit dual-supply translating transceiver with 3-state outputs, manufactured using sub-micron CMOS technology. It interfaces between a 5V bus (A Port) and a 3V bus (B Port). Recommended operating conditions specify VCCA from 4.5V to 5.5V and VCCB from 2.7V to 3.6V. The device operates within a free air temperature range of -40°C to +85°C. Outputs source/sink 24 mA at the 5V bus and 12 mA at the 3V bus. Propagation delay is typically 5.1 ns for A-to-B and 5.4 ns for B-to-A directions.

Translators, Level Shifters Procurement Notes

Verify the specific ordering code against current manufacturer databases due to historical nomenclature changes during the Fairchild Semiconductor integration. Confirm that the suffix 'X' indicates tape and reel packaging. Ensure compatibility with system power-up sequencing requirements to prevent bus contention or oscillations during initialization.

Translators, Level Shifters Selection Notes

Select this component when designing mixed-mode systems requiring translation between 5V and 3V logic domains. The device supports bidirectional data flow controlled by Transmit/Receive inputs. Designers should consider the pin compatibility with 74 series 245 devices for board layout flexibility. Verify that the application environment falls within the specified temperature and voltage operating ranges.

Translators, Level Shifters Part Context

This device belongs to the LVX family of low-voltage CMOS translating transceivers. It serves as a bridge for mixed-signal environments where different voltage standards coexist. The MTCX designation identifies the 24-lead Thin Shrink Small Outline Package variant. The product line addresses the need for efficient signal translation without speed degradation associated with current limiting resistors.

Translators, Level Shifters Replacement Considerations

Direct functional substitutes include MC74LVX4245DTR2G and 74LVX4245WM. Verify package compatibility, as alternatives may utilize SOIC or QSOP formats instead of TSSOP. Ensure electrical characteristics match the required 5V and 3V supply specifications.
