MC74LCX245MNTWG

Overview

The MC74LCX245MNTWG is an octal bus transceiver manufactured by onsemi, belonging to the 74LCX logic family. It features a single circuit with eight bidirectional channels in a TSSOP-20 package. The device operates within a supply voltage range of 2 V to 3.6 V and supports LVTTL/TTL input levels with LVCMOS output levels. Key electrical parameters include a propagation delay of 8 ns, maximum power supply current of 10 uA, and output drive currents of ±24 mA. It functions at non-inverting polarity with three-state outputs across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission across eight independent channels for efficient bus management.
• Features low standby power consumption suitable for battery-operated systems.
• Ensures signal integrity through controlled rise and fall times and reduced crosstalk.
• Supports mixed 5-V and 3-V VCC environments via flexible input/output compatibility.

Applications

• Mobile handheld devices requiring low-power data transfer
• Consumer electronics utilizing high-density bus architectures
• Portable computing equipment with limited power budgets

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during assembly processes.

Selection Notes

Select this component when designing systems requiring low-voltage operation between 2 V and 3.6 V. Consider its TSSOP-20 package for space-constrained PCB layouts. Evaluate the 8 ns propagation delay against system timing constraints to ensure adequate performance for high-speed data buses.
