SN74ABT162501DL

Universal Bus Functions Overview

The SN74ABT162501DL is an 18-bit universal bus transceiver utilizing BiCMOS technology. It operates on a 4.5V to 5.5V supply voltage and features 3-state outputs with high-impedance states during power-up/down. The device supports transparent, latched, or clocked data flow modes via dedicated control inputs. It includes equivalent 25-ohm series resistors at B-port outputs to minimize signal overshoot and undershoot. The component is housed in a 56-pin SSOP package and is rated for operation from -40°C to +85°C.

Universal Bus Functions Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-56 package configuration required for your design. Confirm that the RoHS compliance status matches your manufacturing standards. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental specifications before finalizing procurement.

Universal Bus Functions Selection Notes

Select this component when designing systems requiring 18-bit wide data paths with mixed storage capabilities. It is suitable for applications needing both latch and flip-flop functionality within a single transceiver. Consider the integrated output resistance if external termination components are undesirable. Verify compatibility with 5V logic levels and ensure adequate thermal management for the SSOP package.

Universal Bus Functions FAQ

How does the device handle data flow direction?

Data flow is controlled by complementary output-enable inputs (OEAB and OEBA). When OEAB is active, data flows from A to B; when OEBA is active, data flows from B to A.

What is the function of the internal series resistors?

The B-port outputs include equivalent 25-ohm series resistors designed to reduce overshoot and undershoot, eliminating the need for external resistors.
