Frequently Asked Questions
What is the output current and load capacitance of the SN74ALS533ADW?
The SN74ALS533ADW has a maximum output sink current (I_ol) of 24mA and a specified load capacitance (CL) of 50pF, making it suitable for driving standard TTL and CMOS bus loads in high-speed digital systems.
What package does the SN74ALS533ADW come in and is it Pb-free?
The SN74ALS533ADW is housed in a 20-pin SOIC package (JESD-30 code R-PDSO-G20). It is Pb-free compliant with JESD-609 code e4, meeting RoHS requirements for lead-free manufacturing.
What are typical applications for the SN74ALS533ADW?
Typical applications include microprocessor address and data bus buffering, memory interface latching, FPGA I/O expansion, and industrial control bus management where 8-bit transparent latching with tri-state outputs is required.
What is the difference between the latch enable (LE) and output enable (OE) pins on the SN74ALS533ADW?
The latch enable (LE) is active-high: when HIGH, data flows transparently from inputs to outputs; when LOW, the last data state is latched. The output enable (OE) is active-low: when LOW, outputs are active; when HIGH, outputs are placed in a high-impedance (tri-state) condition, disconnecting the device from the bus.
