SN74ABT16600DL

Universal Bus Functions Overview

The SN74ABT16600DL is an 18-bit universal bus transceiver from the Texas Instruments 74ABT series, housed in a 56-pin SSOP (DL) package. It operates on a supply voltage of 4.5 V to 5.5 V and supports data rates up to 150 MHz. The device features 3-state outputs with high-level output current of -32 mA and low-level output current of 64 mA. Propagation delays range from 1.5 ns to 5.1 ns depending on direction and load conditions (CL = 50 pF). It functions within a temperature range of -40 °C to +85 °C.

Universal Bus Functions Feature Summary

• ESD protection exceeds 2000 V per MIL-STD-883, Method 3015
• Latch-up performance exceeds 500 mA per JEDEC Standard JESD-17

Universal Bus Functions Applications

• High-speed data transfer between buses
• Memory interface circuits
• Buffering applications requiring registered data flow

Universal Bus Functions Procurement Notes

Verify component status as the SN74ABT16600DL is listed as obsolete in official documentation. Confirm availability through authorized distributors or secondary markets. Ensure the specific DL package variant matches design requirements. Check for RoHS compliance details if required by project specifications. Validate that the operating temperature range meets environmental constraints.

Universal Bus Functions Selection Notes

Select this component for designs requiring 18-bit bidirectional data transfer with flexible control modes. The ABT BiCMOS technology offers reduced power dissipation compared to older logic families. Consider the 56-pin SSOP package dimensions for board space limitations. Evaluate the 150 MHz maximum frequency against system timing requirements. Ensure pull-up resistors are used on OE pins for proper power-up behavior.

Universal Bus Functions Part Context

Part of the Widebus family utilizing EPIC-IIB BiCMOS design. The UBT feature allows versatile data handling modes. Similar devices include the SN74ABT16601 and SN74ABT16470, though pinouts and specific control inputs may differ. The SN54ABT16600 is the military-grade equivalent with extended temperature range.

Universal Bus Functions Replacement Considerations

The SN74ABT16600DL is marked obsolete. Potential substitutes include the SN74ABT16601DGGR or SN74ABT16601DLR, which offer similar 18-bit functionality but may have different control pin configurations. Verify electrical compatibility and pinout alignment before substitution.

Universal Bus Functions FAQ

What are the control inputs for data flow direction?

Data flow is controlled by output-enable (OEAB/OEBA), latch-enable (LEAB/LEBA), and clock (CLKAB/CLKBA) inputs.

How does the device handle power-up states?

To ensure a high-impedance state during power-up or power-down, OE should be tied to VCC through a pullup resistor.

What is the maximum operating frequency?

The maximum clock frequency is 150 MHz under recommended operating conditions.
