Overview
The SN74LVTH16501DLR is an 18-bit universal bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 3.6V and supports high-drive outputs with 32mA high-level and 64mA low-level current capabilities. The device features a 56-pin SSOP package, functions across a temperature range of -40°C to +85°C, and utilizes ABT logic technology for efficient data transmission in bus-oriented applications.
Feature Summary
- Provides bidirectional data transfer capability via 18-bit universal bus architecture
- Delivers strong output drive strength suitable for direct interface with buses and loads
- Supports standard surface-mount installation using a compact 56-SSOP form factor
Applications
- High-density memory modules requiring wide data path interfacing
- Bus-oriented systems utilizing 3-state output control
- Consumer electronics with 3.3V logic level requirements
Procurement Notes
Verify the specific ordering suffix 'DLR' to confirm the tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints designed for the 56-SSOP package. Confirm that the 2.7V to 3.6V operating voltage aligns with the target system power rails before finalizing procurement decisions.
Selection Notes
Select this component when an 18-bit width is required for parallel data handling. The ABT technology offers a balance between speed and power consumption compared to older families. Consider the 56-SSOP package constraints regarding board space and thermal dissipation during the design phase.
Part Context
This part belongs to the SN74LVTH series, representing Texas Instruments' Low Voltage TTL-compatible logic family. These devices are engineered for 3.3V systems while maintaining compatibility with legacy 5V interfaces through appropriate level shifting or tolerance specifications.
Replacement Considerations
The SN74LVTH16501DGGR serves as a pin-compatible alternative in a TSSOP-56 package. Verify mechanical fit and electrical parameters against the original SSOP specification before substitution.
