CMOS Digital Integrated Circuits Silicon Monolithic
74LCX273FT
1. Functional Description
•
Low-Voltage Octal D-Type Flip-Flop with Clear with 5-V Tolerant Inputs and Outputs
2. General
The74LCX273FTisahigh-performanceCMOSoctalD-typeflip-flop. Designedforusein3.3Vsystems, itachieves
high-speed operation while maintaining the CMOS low-power dissipation.
The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5 V supply
environment for both inputs and outputs.
This 8 bit D-type flip-flop is controlled by a clock input (CK) and a clear input (CLR). When the CLR input is low,
the eight outputs are at a low logic level.
All inputs are equipped with protection circuits against static discharge.
3. Features
(1) AEC-Q100 (Rev. H) (Note 1)
(2) Wide operating temperature range: Topr = -40 to 125
(3) Low-voltage operation: VCC = 1.65 to 3.6 V
(4) High-speed operation: tpd = 9.5 ns (max) (VCC = 3.3 ± 0.3 V)
(5) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)
(6) Power-down protection provided on all inputs and outputs
(7) Pin and function compatible with the 74 series
(74LVC/ALVC/ etc.) 273 type
Note 1: This device is compliant with the reliability requirements of AEC-Q100. For details, contact your Toshiba sales
representative.

Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“HandlingPrecautions”/“DeratingConceptandMethods”)andindividualreliabilitydata(i.e. reliabilitytestreport
and estimated failure rate, etc).
Note 1: VCC = 0 V
Note 2: High (H) or Low (L) state. IOUT absolute maximum rating must be observed.
Note 3: VOUT < GND, VOUT > VCC
Note 4: 180 mW in the range of Ta = -40 to 85 . From Ta = 85 to 125 a derating factor of -3.25 mW/ shall be
applied until 50 mW.
