MC74VHC50
Hex Buffer
The MC74VHC50 is an advanced high speed CMOS buffer fabricated with silicon gate CMOS technology.
The internal circuit is composed of three stages, including a buffered output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems to 3 V systems.
• High Speed: tPD = 3.8 ns (Typ) at VCC = 5 V • Low Power Dissipation: ICC = 2 mA (Max) at TA = 25°C • High Noise Immunity: VNIH = VNIL = 28% VCC • Power Down Protection Provided on Inputs • Balanced Propagation Delays • Designed for 2 V to 5.5 V Operating Range • Low Noise: VOLP = 0.8 V (Max) • These Devices are Pb−Free and are RoHS Compliant

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. Measured with minimum pad spacing on an FR4 board, using 10 mm−by−1 inch, 2−ounce copper trace with no air flow. 2. Tested to EIA/JESD22−A114−A. 3. Tested to EIA/JESD22−A115−A. 4. Tested to JESD22−C101−A. 5. Tested to EIA/JESD78.
