Overview
The CD74HC243MT is a high-speed CMOS logic quad-bus transceiver manufactured by Texas Instruments. It features four non-inverting channels with three-state outputs in a 14-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55 °C to +125 °C. Key electrical parameters include maximum high-level output current of -7.8 mA and low-level output current of 7.8 mA. Propagation delay is specified at 90 ns @ 2 V with a 50 pF load.
Feature Summary
- Provides four non-inverting bus transceiver channels for data direction control
- Features three-state outputs to facilitate bus-oriented systems
- Supports wide supply voltage operation suitable for various logic families
Applications
- Bus-oriented systems requiring data direction control
- Memory and memory mapping circuits
- Clock drivers and buffer circuits
Procurement Notes
Verify the specific suffix 'M' indicates the SOIC-14 surface-mount package configuration. Confirm that the component meets RoHS compliance standards as indicated by manufacturer documentation. Ensure the ordering part number matches the exact speed grade and package variant required for the design.
Selection Notes
Select this component when a quad-channel, non-inverting bus transceiver with three-state capability is required. The HC series offers compatibility with standard CMOS logic levels. Consider the 2 V to 6 V operating range for flexibility in power supply designs compared to fixed 5 V devices.
Part Context
This component belongs to the Texas Instruments HC series of high-speed CMOS logic devices. It functions as a quad-bus transceiver, distinct from octal variants like the SN74HC245. The device is designed for applications requiring bidirectional data flow control on multiple lines simultaneously.
Replacement Considerations
Compatible substitutes include other quad-bus transceivers such as the CD74HC243M or equivalent parts from other manufacturers offering identical pinouts and logical functionality.
