Frequently Asked Questions
What output current can the SN74BCT2241DWRG4 sink per channel?
Each output of the SN74BCT2241DWRG4 can sink up to 12 mA (I_OL = 0.012 A), making it suitable for driving standard TTL and CMOS logic loads as well as bus lines with moderate current requirements.
What is the purpose of the 33-ohm output series resistors in this device?
The integrated 33-ohm series resistors dampen transmission line reflections and reduce overshoot on PCB signal traces, improving signal integrity especially at high switching frequencies or on boards with long trace lengths and 50 pF load capacitance.
How does the output-enable logic work on the SN74BCT2241DWRG4?
The device features two output-enable controls: one active-high and one active-low. Both must be in their active states simultaneously to enable the outputs; otherwise all 8 outputs enter the high-impedance (3-state) mode, allowing safe bus sharing with other drivers.
What package does the SN74BCT2241DWRG4 use, and how many pins does it have?
The SN74BCT2241DWRG4 comes in a 20-pin Small Outline Package (SOIC), specifically the R-PDSO-G20 package, which is a standard surface-mount package compatible with automated PCB assembly processes.
What are common applications for the SN74BCT2241DWRG4?
This device is commonly used in embedded processor bus buffering, industrial PLC I/O expansion, backplane data distribution, and memory interface circuits where multiple 3-state drivers must share a common bus without contention.
