74F533PC

Latches Overview

The onsemi 74F533PC is an octal transparent latch with 3-STATE outputs designed for bus-oriented system applications. It contains eight D-type latches and operates within a supply voltage range of +4.5V to +5.5V. The device features inverted outputs, distinguishing it from the non-inverted 74F373. Data enters the latches when Latch Enable (LE) is HIGH and is stored upon the HIGH-to-LOW transition of LE. The 3-STATE buffers are controlled by the Output Enable (OE) input; OE LOW enables bi-state mode, while OE HIGH places outputs in a high impedance state. Propagation delays vary based on load capacitance and temperature.

Latches Feature Summary

• Contains eight D-type latches with 3-STATE output buffers for bus interfacing
• Transparent data path when Latch Enable is HIGH
• Inverted output configuration compared to standard non-inverting latches
• High impedance state control via dedicated Output Enable input

Latches Applications

• Bus organized system applications
• Data storage in digital logic circuits
• Bus interfacing requiring tri-state control

Latches Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and material composition details prior to integration. Ensure the specific PDIP package variant matches design requirements. Check for obsolescence notices as this component originates from legacy Fairchild Semiconductor documentation now managed under onsemi branding.

Latches Selection Notes

Select this component for designs requiring octal latching with inverted outputs and bus isolation capabilities. Compare propagation delay specifications against system timing constraints at the intended operating temperature. Verify that the 20-lead PDIP package fits the PCB layout. Consider the 74F373 if non-inverted outputs are required instead.

Latches Part Context

This part belongs to the 74F series of high-speed TTL-compatible logic devices. Originally manufactured by Fairchild Semiconductor, the product line is now supported by onsemi. The 74F533 serves as the inverted counterpart to the 74F373, providing identical functionality with complemented outputs for specific logic inversion needs in bus architectures.

Latches Replacement Considerations

SN74F373N is a parameter equivalent alternative available from Texas Instruments.
