Overview
The MC74HC245AFL2 is an octal bus transceiver featuring non-inverting logic and three-state outputs. It operates within a supply voltage range of 2V to 6V, with output drive currents of 7.8mA for both high and low states. The device supports propagation delays of up to 110ns and functions reliably across an extended temperature range from -55°C to +125°C. Packaged in a 20-SOIC format, it facilitates efficient data transfer in digital systems requiring robust signal integrity and low power consumption.
Feature Summary
- Octal configuration providing eight independent bidirectional data paths
- Three-state outputs enabling direct connection to system buses without additional drivers
- Non-inverting logic design ensuring signal polarity preservation during transmission
Applications
- High-performance networking equipment signal processing
- Digital consumer electronics internal data routing
- Industrial control systems requiring reliable bus interfacing
Procurement Notes
Verify the manufacturer origin carefully, as listings may attribute this part to Motorola, NXP, or Onsemi due to historical acquisitions. Confirm the specific suffix 'FL2' matches your board requirements. Ensure the datasheet aligns with the claimed electrical specifications before finalizing orders.
Selection Notes
Select this component when an octal, non-inverting transceiver with three-state capability is required for bus applications. Consider the 2V to 6V operating range and SOIC-20 package constraints. Verify compatibility with existing logic families and thermal management needs for industrial environments.
Part Context
This component belongs to the HC (High-speed CMOS) logic family, known for speed comparable to LS TTL but with lower power consumption. The MC74HC245 series is widely used for driving heavy loads and connecting microprocessors to memory or I/O devices in complex digital circuits.
Replacement Considerations
The MC74HC245ADWR2G-Q is a documented alternative from Onsemi offering similar octal bus transceiver functionality. Verify pinout compatibility and electrical parameters against the original specification sheet before substitution.
