Inputs can be driven from either 3.3V or 5V devices. In 3-State operation, outputs can handle 5V. These features allow the use of these devices in a mixed 3.3V/5V environment. The 74LVCH16541A is a 16-bit inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs 1OEn and 2OEn. A HIGH on nOEn causes the outputs to assume a high impedance OFF-state. To ensure the high impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 2Y2 16 33 2A2 2Y3 17 32 2A3 VCC 18 31 VCC 2Y4 19 30 2A4 2Y5 20 29 2A5 GND 21 28 GND 2Y6 22 27 2A6 2Y7 23 26 2A7 2OE1 24 25 2OE2 SW00113 QUICK REFERENCE DATA GND = 0V; Tamb = 25°C; tr = tf ≤ 2.5ns PARAMETER SYMBOL tPHL/tPLH Propagation delay 1An to 1Yn; 2An to 2Yn CI Input capacitance CPD CONDITIONS TYPICAL UNIT 2.7 ns 5.0 pF 32 5 pF CL = 50pF VCC = 3.3V Power dissipation capacitance per buffer VI = GND to VCC outputs enabled output disabled 1 NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL × VCC2 × fo) = sum of outputs.

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output voltage ratings may be exceeded if the input and output clamp current ratings are observed. 1998 May 19 4 Philips Semiconductors Product specification 16-bit buffer/line driver; 5V tolerant I/O (3-State) 74LVCH16541A DC CHARACTERISTICS Over recommended operating conditions Voltages are referenced to GND (ground = 0V) LIMITS SYMBOL PARAMETER TEST CONDITIONS Temp = -40°C to +85°C MIN VIH HIGH level input voltage VIL LOW level input voltage VOH O VOL VCC = 1.2V VCC VCC = 2.7 to 3.6V 2.0 TYP1 LOW level output voltage MAX V VCC = 1.2V GND V VCC = 2.7 to 3.6V HIGH level output voltage UNIT 0.8 VCC = 2.7; VI = VIH or VIL; IO = –12mA VCC-0.5 VCC = 3.0V; VI = VIH or VIL; IO = –100µA VCC-0.2 VCC = 3.0V; VI = VIH or VIL; IO = –18mA VCC-0.6 VCC = 3.0V; VI = VIH or VIL; IO = –24mA VCC-0.8 VCC V VCC = 2.7V; VI = VIH or VIL; IO = 12mA 0.40 VCC = 3.0V; VI = VIH or VIL; IO = 100µA 0.20 VCC = 3.0V; VI = VIH or VIL; IO = 24mA 0.55 V Input leakage current VCC = 3.6V; VI = 5.5V or GND6 0.1 5 µA IOZ 3-State output OFF-state current VCC = 3.6V; VI = VIH or VIL; VO = 5.5V or GND 0.1 5 µA IOFF Power off leakage current VCC = 0.0V; VI or VO = 5.5V 0.1 ±10 µA ICC Quiescent supply current VCC = 3.6V; VI = VCC or GND; IO = 0 0.1 20 µA ∆ICC Additional quiescent supply current given per input pin VCC = 2.7 to 3.6V; VI = VCC – 0.6V; IO = 0 5 500 µA IBHL Bus hold LOW sustaining current VCC = 3.0V; VI = 0.8V2, 3, 4 75 µA IBHH Bus hold HIGH sustaining current VCC = 3.0V; VI = 2.0V2, 3, 4 –75 µA IBHLO Bus hold LOW overdrive current VCC = 3.6V2, 3, 5 500 µA IBHHO Bus hold HIGH overdrive current VCC = 3.6V2, 3, 5 –500 µA II NOTES: 1. All typical values are at VCC = 3.3V and Tamb = 25°C. 2. Valid for data inputs of bus hold parts (LVCH16-A) only. 3. For data inputs only, control inputs do not have a bus hold circuit. 4. The specified sustaining current at the data input holds the input below the specified VI level. 5. The specified overdrive current at the data input forces the data input to the opposite logic input state. 6. For bus hold parts, the bus hold circuit is switched off when Vi exceeds VCC allowing 5.5V on the input terminal. 1998 May 19 5 Philips Semiconductors Product specification 74LVCH16541A 16-bit buffer/line driver; 5V tolerant I/O (3-State) AC CHARACTERISTICS GND = 0V; tR = tF ≤ 2.5ns; CL = 50pF; RL = 500Ω; Tamb = –40°C to +85°C.
