MC74VHCT126A Quad Bus Buffer with 3−State Control Inputs The MC74VHCT126A is a high speed CMOS quad bus buffer fabricated with silicon gate CMOS technology. It achieves noninverting high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The MC74VHCT126A requires the 3−state control input (OE) to be set Low to place the output into high impedance. The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V, because it has full 5.0 V CMOS level output swings. The VHCT126A input structures provide protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. The output structures also provide protection when VCC = 0 V. These input and output structures help prevent device destruction caused by supply voltage − input/output voltage mismatch, battery backup, hot insertion, etc. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems. http://onsemi.com MARKING DIAGRAMS 14 SOIC−14 D SUFFIX CASE 751A 1 1 14 High Speed: tPD = 3.8 ns (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 4.0 mA (Max) at TA = 25°C TTL−Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V Power Down Protection Provided on Inputs Balanced Propagation Delays Designed for 2.0 V to 5.5 V Operating Range Low Noise: VOLP = 0.8 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300 mA ESD Performance: HBM > 2000 V; Machine Model > 200 V Chip Complexity: 72 FETs or 18 Equivalent Gates These Devices are Pb−Free and are RoHS Compliant VHCT 126A ALYWG G TSSOP−14 DT SUFFIX CASE 948G 1 1 14 Features • • • • • • • • • • • • VHCT126AG AWLYWW SOEIAJ−14 M SUFFIX CASE 965 1 VHCT126 ALYWG 1 A WL, L Y WW, W G or G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package See Applications Note #AND8004/D for date code and traceability information.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V CC ). Unused outputs must be left open.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC / 4 (per buffer). CPD is used to determine the no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC. http://onsemi.com 3 MC74VHCT126A NOISE CHARACTERISTICS (Input tr = tf = 3.0ns, CL = 50pF, VCC = 5.0V) TA = 25°C Symbol Typ Max Unit Quiet Output Maximum Dynamic VOL VOLP 0.3 0.8 V Quiet Output Minimum Dynamic VOL VOLV − 0.3 − 0.8 V Minimum High Level Dynamic Input Voltage VIHD 3.5 V Maximum Low Level Dynamic Input Voltage VILD 1.5 V Characteristic SWITCHING WAVEFORMS 3.0V OE 3.0V A 1.5V GND 1.5V tPZL GND tPHL tPLH Y Y VOH 1.5V tPLZ HIGH IMPEDANCE 1.5V tPZH VOL VOL + 0.3V tPHZ VOH - 0.3V Y 1.5V Figure 3.
