These devices provide speed and drive capabilities equivalent to their fastest bipolar-logic counterparts, while reducing power dissipation. The input and output voltage levels allow direct interface with TTL, NMOS, and CMOS devices without external components. These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample-and-hold techniques are preferable to minimize internal chip heating and more accurately reflect operational values. Otherwise, prolonged shorting of a high output can raise the chip temperature well above normal and cause invalid readings in other parametric tests. In any sequence of parameter tests, IOS tests should be performed last. § Per TTL-driven input (VIN = 3.4 V); all other inputs at VCC or GND ¶ This parameter is derived for use in total power-supply calculations. 4 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 CY54FCT541T, CY74FCT541T 8-BIT BUFFERS/LINE DRIVERS WITH 3-STATE OUTPUTS SCCS072 – OCTOBER 2001 electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) (continued) PARAMETER CY54FCT541T TYP† MAX TEST CONDITIONS VCC = 5.5 V, Outputs Out uts o open en, OEA = OEB = GND or OEA = GND and OEB = VCC One bit switching at f1 = 10 MHz at 50% duty cycle VCC = 5.25 V, Out uts o en, Outputs open OEA = OEB = GND or OEA = GND and OEB = VCC One bit switching at f1 = 10 MHz at 50% duty cycle IC# Eight bits switching at f1 = 2.5 MHz at 50% duty cycle MIN VIN ≤ 0.2 V or VIN ≥ VCC – 0.2 V VIN = 3.4 V or GND VIN ≤ 0.2 V or VIN ≥ VCC – 0.2 V VIN = 3.4 V or GND VIN ≤ 0.2 V or VIN ≥ VCC – 0.2 V 0.7 1.4 1 2.4 1.3 2.6|| 3.3 10.6|| CY74FCT541T TYP† MAX MIN UNIT mA 0.7 1.4 1 2.4 1.3 2.6|| 3.3 10.6|| Ci 5 10 pF Co 9 12 pF Eight bits switching at f1 = 2.5 MHz at 50% duty cycle VIN = 3.4 V or GND VIN ≤ 0.2 V or VIN ≥ VCC – 0.2 V VIN = 3.4 V or GND † Typical values are at VCC = 5 V, TA = 25°C. # IC = ICC + ∆ICC × DH × NT + ICCD (f0/2 + f1 × N1) Where: IC = Total supply current ICC = Power-supply current with CMOS input levels ∆ICC = Power-supply current for a TTL high input (VIN = 3.4 V) DH = Duty cycle for TTL inputs high NT = Number of TTL inputs at DH ICCD = Dynamic current caused by an input transition pair (HLH or LHL) f0 = Clock frequency for registered devices, otherwise zero f1 = Input signal frequency N1 = Number of inputs changing at f1 All currents are in milliamperes and all frequencies are in megahertz. || Values for these conditions are examples of the ICC formula.
