TC74LCX126F/FT/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX126F,TC74LCX126FT,TC74LCX126FK
Low-Voltage Quad Bus Buffer with 5-V Tolerant Inputs and Outputs
The TC74LCX126 is a high-performance CMOS quad bus buffers. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for inputs. This device requires the 3-state control input (OE) to be set high to place the output into the high impedance state. All inputs are equipped with protection circuits against static discharge.

Absolute Maximum Ratings (Note 1)
Characteristics Power supply voltage DC input voltage DC output voltage Input diode current Output diode current DC output current Power dissipation DC VCC/ground current Storage temperature Symbol VCC VIN VOUT IIK IOK IOUT PD ICC/IGND Tstg Rating -0.5 to 7.0 -0.5 to 7.0 -0.5 to 7.0 (Note 2) -0.5 to VCC + 0.5 (Note 3) -50 50 50 180 100 -65 to 150 (Note 4) V mA mA mA mW mA C Unit V V
Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating range (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 2: Output in OFF state Note 3: High or low state. IOUT absolute maximum rating must be observed. Note 4: VOUT < GND, VOUT > VCC
