Overview
The SN74ALS32DBR is a quad two-input positive-OR gate integrated circuit manufactured by Texas Instruments. It belongs to the 74ALS logic family and is housed in a 14-pin SSOP surface-mount package. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical characteristics include a maximum propagation delay of 10ns at 5V with a 50pF load, a low-level output current of 24mA, and a high-level output current of -8mA. It functions reliably across an operating temperature range of 0°C to 70°C.
Feature Summary
- Provides four independent two-input OR logic gates in a single compact package
- Features high-speed switching capabilities typical of the Advanced Low-power Schottky series
- Delivers strong output drive capability suitable for interfacing with various digital loads
Applications
- Digital signal processing circuits requiring logical OR operations
- Address decoding networks in microprocessor-based systems
- Data bus selection and routing logic
Procurement Notes
Verify the specific suffix 'DBR' corresponds to the 14-SSOP package and tape-and-reel quantity. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the source document explicitly lists SN74ALS32DBR rather than generic family members. Check for any specific handling requirements related to the SSOP form factor during assembly.
Selection Notes
Select this component when a balance of speed and power consumption is required compared to standard LS or ALS families. The SSOP package is appropriate for space-constrained printed circuit board designs. Verify that the 24mA sink current meets the fan-out requirements of the connected inputs. Consider the 10ns delay performance against system timing constraints.
Part Context
This part is part of the Texas Instruments 74ALS series, which offers improved speed and power dissipation characteristics over the standard 74LS series. The SN74ALS32 provides the fundamental OR function, serving as a building block for more complex combinational logic circuits. It is distinct from the SN74AS32, which offers even higher speed but different power characteristics.
FAQ
What is the maximum propagation delay for the SN74ALS32DBR?
The maximum propagation delay is 10ns when tested at a supply voltage of 5V with a 50pF load capacitance.
Does the SN74ALS32DBR support through-hole mounting?
No, the SN74ALS32DBR is specifically designed for surface-mount technology using a 14-SSOP package.
