IDTQS74FCT153AT/CT
DESCRIPTION:
CMOS power levels: <7.5mW static Undershoot clamp diodes on all inputs True TTL input and output compatibility Ground bounce controlled outputs Reduced output swing of 0 to 3.5V A and C grades with 4.5ns tPD for C IOL = 48mA Available in SOIC and QSOP packages
The IDTQS74FCT153T is a high-speed CMOS TTL-compatible dual 4-input multiplexer. All inputs have clamp diodes for undershoot noise suppression. All outputs have ground bounce suppression. Outputs will not load an active bus when Vcc is removed from the device.

NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

POWER SUPPLY CHARACTERISTICS
Symbol ICC Parameter Quiescent Power Supply Current Test Conditions(1) VCC = Max. freq = 0 0V VIN 0.2V or VCC - 0.2V VIN VCC ICC Supply Current per Input TTL Inputs HIGH VCC = Max. VIN = 3.4V(2) freq = 0 VCC = Max. Outputs Open and Enabled One Bit Toggling 50% Duty Cycle Other inputs at GND or VCC(3,4)
NOTES: 1. For conditions shown as Min. or Max., use appropriate value specified under DC Electrical Characteristics. 2. Per TTL driven input (VIN = 3.4V). 3. For flip-flops, ICCD is measured by switching one of the data input pins so that the output changes every clock cycle. This is a measurement of device power consumption only and does not include power to drive load capacitance or tester capacitance. 4. IC = IQUIESCENT + IINPUTS + IDYNAMIC IC = ICC + ICC DHNT + ICCD (fCP/2 + fiNi) ICC = Quiescent Current ICC = Power Supply Current for a TTL High Input (VIN = 3.4V) DH = Duty Cycle for TTL Inputs High NT = Number of TTL Inputs at DH ICCD = Dynamic Current caused by an Output Transition Pair (HLH or LHL) fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices) fi = Output Frequency Ni = Number of Outputs at fi All currents are in milliamps and all frequencies are in megahertz.
