74LVCH162245ADGG:5

Overview

The Nexperia 74LVCH162245ADGG:5 is a 16-bit bus transceiver with non-inverting 3-state outputs, housed in a TSSOP48 package (SOT362-1). It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V. The device features integrated 30 Ω series termination resistors and bus hold circuitry on all data inputs. It includes two direction control inputs (1DIR, 2DIR) and two output enable inputs (1OE, 2OE), allowing configuration as one 16-bit or two 8-bit transceivers.

Feature Summary

• Integrated 30 Ω series termination resistors for noise reduction
• Bus hold functionality on all data inputs eliminates external pull-up requirements
• Dual output enables facilitate easy cascading and bus isolation
• High-impedance state when powered down prevents backflow current

Applications

• Mixed 3.3 V and 5 V logic environments
• Multibyte flow-through standard pin-out architectures
• Partial power-down applications requiring I_OFF protection

Procurement Notes

Verify the specific ordering suffix ':5' against official Nexperia documentation to confirm packaging details, as datasheets typically list 'ADGG' without this suffix. Ensure the component matches the TSSOP48 (SOT362-1) physical dimensions and electrical specifications defined in the Rev 6 product data sheet before finalizing procurement.

Selection Notes

Select this component for designs requiring low-power CMOS operation with direct TTL interface capabilities. The inclusion of bus hold circuits simplifies board layout by removing the need for external pull-up resistors on unused inputs. Verify that the application environment remains within the specified -40 °C to +125 °C temperature range.

Part Context

This device belongs to the 74LVC(H)162245A family of high-performance, low-voltage silicon-gate CMOS devices. Originally developed under NXP Semiconductors, the business was transferred to Nexperia in February 2017. The part is designed to be superior to most advanced CMOS compatible TTL families while maintaining backward compatibility.

Replacement Considerations

The 74LVC162245ADGG is the base variant within the same family. Verify if the ':5' suffix indicates a specific tape-and-reel quantity or packaging variation rather than a functional difference.
