74LVCH16541ADGG:11

Overview

The Nexperia 74LVCH16541ADGG:11 is a 16-bit buffer and line driver featuring three-state outputs controlled by two output enable inputs (1OEn and 2OEn). It operates within a supply voltage range of 1.2 V to 3.6 V, with inputs tolerant up to 5.5 V for mixed 3.3 V and 5 V applications. The device utilizes a TSSOP48 package (SOT362-1) and includes bus hold on all data inputs. Propagation delay ranges from 1.0 ns to 12.0 ns depending on voltage. Operating temperature spans -40 °C to +125 °C.

Feature Summary

• Features five-volt tolerant inputs and outputs for interfacing with 5 V logic systems.
• Includes bus hold circuitry on all data inputs to eliminate the need for external pull-up resistors.
• Provides high-impedance outputs when the supply voltage is zero volts.

Applications

• Mixed 3.3 V and 5 V system environments
• Buffering and line driving applications
• General-purpose digital signal routing

Procurement Notes

Verify the specific ordering suffix :11 against the manufacturer's current catalog to ensure correct packaging configuration. Confirm that the TSSOP48 plastic thin shrink small outline package meets your board layout requirements. Check the latest product status documentation to confirm active production availability before finalizing design-in decisions.

Selection Notes

Select this component when designing circuits requiring 16-bit buffering with three-state control in mixed voltage environments. Ensure the application operates within the specified 1.2 V to 3.6 V supply range. Verify that the input signals do not exceed the 5.5 V tolerance limit. Consider the thermal dissipation capabilities if operating at the upper end of the temperature range.

Part Context

This part belongs to the 74LVCH16541A family of 16-bit buffers and line drivers. It is manufactured by Nexperia USA Inc. and is housed in a SOT362-1 (TSSOP48) package. The device is designed for low-power CMOS applications and complies with various JEDEC standards for different voltage ranges.

Replacement Considerations

Consult official Nexperia documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully when considering alternatives from other manufacturers.

FAQ

How are the three-state outputs controlled?

The outputs are controlled by two active LOW output enable inputs (1OEn and 2OEn). A HIGH level on either nOEn causes the corresponding outputs to assume a high-impedance OFF-state.

What is the function of the bus hold feature?

Bus hold on the data inputs eliminates the need for external pull-up resistors to hold unused inputs at a defined logic level.
