Overview
The onsemi 74LCX2244SJX is a low-voltage CMOS octal buffer and line driver featuring 5V-tolerant inputs and outputs. It operates within a supply voltage range of 2.3V to 3.6V, with a maximum quiescent current of 10µA. The device provides ±12mA output drive at 3.0V and includes 26Ω series resistors in the outputs to reduce overshoot and undershoot. Propagation delay is specified as 7.5ns maximum at 3.3V. It utilizes a 20-lead SOP package.
Feature Summary
- Features integrated 26Ω series resistors in the outputs to minimize signal overshoot and undershoot.
- Supports live insertion and withdrawal capabilities for system flexibility.
- Provides 5V tolerance on both inputs and outputs for mixed-voltage interfacing.
- Implements patented noise and EMI reduction circuitry.
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented transmitter/receiver applications
Procurement Notes
Verify the specific ordering code suffix 'X' corresponds to tape and reel packaging when sourcing this component. Confirm that the manufacturer documentation explicitly supports the requested package type and revision level before finalizing procurement decisions.
Selection Notes
Select this component for designs requiring high-speed buffering with inherent output impedance control. The 5V tolerance allows direct interfacing between low-voltage logic and 5V environments without additional level shifting components.
Part Context
This part belongs to the LCX family of low-voltage CMOS logic devices. It is manufactured by Fairchild Semiconductor (now onsemi) and serves as an octal buffer with three-state outputs designed for low power dissipation and high-speed operation.
Replacement Considerations
Check datasheets for equivalent parts from other manufacturers to ensure pin compatibility and electrical parameter alignment. Verify if alternative packages are available if the SOP form factor is not suitable for the target application.
FAQ
What is the function of the internal series resistors?
The 26Ω series resistors help reduce output overshoot and undershoot during signal transitions.
How does the device handle power-down states?
The device features power-down high impedance inputs and outputs to prevent unwanted current flow.
