The MC74VHC245 is an advanced high speed CMOS octal bustransceiver fabricated with silicon gate CMOS technology. It achieves highspeed operation similar to equivalent Bipolar Schottky TTL while maintainingCMOS low power dissipation.

It is intended for two–way asynchronous communication between databuses. The direction of data transmission is determined by the level of theDIR input. The output enable pin (OE) can be used to disable the device, sothat the buses are effectively isolated.

All inputs are equipped with protection circuits against static discharge.

• High Speed: tPD = 4.0ns (Typ) at VCC = 5V• Low Power Dissipation: ICC = 4µA (Max) at TA = 25°C• High Noise Immunity: VNIH = VNIL = 28% VCC• Power Down Protection Provided on Inputs• Balanced Propagation Delays• Designed for 2V to 5.5V Operating Range• Low Noise: VOLP = 1.2V (Max)• Pin and Function Compatible with Other Standard Logic Families• Latchup Performance Exceeds 300mA• ESD Performance: HBM > 2000V; Machine Model > 200V• Chip Complexity: 308 FETs or 77 Equivalent Gates

APPLICATION NOTES

1. Do not force a signal on an I/O pin when it is an active output, damage mayoccur.

2. All floating (high impedence) input or I/O pins must be fixed by means ofpull up or pull down resistors or bus terminator ICs.

3. A parasitic diode is formed between the bus and VCC terminals. Therefore,the VHC245 cannot be used to interface 5V to 3V systems directly.

This device contains protectioncircuitry to guard against damagedue to high static voltages or electricfields. However, precautions mustbe taken to avoid applications of anyvoltage higher than maximum ratedvoltages to this high–impedance cir-cuit. For proper operation, Vin andVout should be constrained to therange GND (Vin or Vout) VCC.

Unused inputs must always betied to an appropriate logic voltagelevel (e.g., either GND or VCC).Unused outputs must be left open.

1. Parameter guaranteed by design. tOSLH = |tPLHm – tPLHn|, tOSHL = |tPHLm – tPHLn|.

2. 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/ 8 (per bit). CPD is used to determine the no–loaddynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
