Frequently Asked Questions
What is the SN74AC533N and what does it do?
The SN74AC533N is an 8-bit D-type transparent latch with 3-state outputs from Texas Instruments. It belongs to the AC logic family and features a DIP-20 package. When the latch enable is high, the Q outputs follow the D inputs; when low, the outputs retain the last data state. It is designed to drive bus lines with a load capacitance up to 50 pF.
What are the key specifications of the SN74AC533N?
Key specifications include: 8-bit (1-of-8) latch configuration, 2-port bus driver, AC logic family, DIP-20 through-hole package, 50 pF rated load capacitance, 3-state outputs for bus sharing, RoHS compliant (JESD-609 e4), and a typical supply voltage of 5 V. The device supports fast switching speeds characteristic of the AC logic series.
What are typical applications for the SN74AC533N?
The SN74AC533N is commonly used in microprocessor address and data bus latching, memory interface circuits, I/O port expansion, and industrial control systems. Its 3-state outputs allow multiple devices to share a common bus without contention, making it ideal for multiprocessor systems and backplane bus architectures.
What package does the SN74AC533N come in and are there SMD alternatives?
The SN74AC533N is available in a DIP-20 (Dual In-Line Package, 20-pin) through-hole package. For surface-mount designs, Texas Instruments offers equivalent devices in SOIC-20 and TSSOP-20 packages, such as the SN74AC533DW or SN74AC533PW, providing the same 8-bit latch functionality in a smaller footprint.
Where can I buy the SN74AC533N and what is the price?
The SN74AC533N is available for purchase at approximately $0.83 per unit, with pricing varying by quantity and distributor. It is stocked by major electronics distributors worldwide. You can submit a quote request on FindMyChip to receive competitive pricing and confirm current stock availability with fast worldwide shipping.
