  • Industrial temperature range of –40˚C to +85˚C
  • V CC = 5V± 10% CY74FCT16240T Features:
  • 64 mA sink current, 32 mA source current
  • Typical VOLP (ground bounce) <1.0V at VCC = 5V, TA = 25˚C CY74FCT162240T Features:
  • Balanced output drivers: 24 mA
  • Reduced system switching noise
  • Typical V OLP (ground bounce) <0.6V at VCC = 5V, TA = 25˚C Functional Description These 16-bit buffer/line drivers are used in memory driver, clock driver, or other bus interface applications, where high speed and low power are required. With flow-through pinout and small shrink packaging, board layout is simplified. The three-state controls are designed to allow 4-, 8-, or 16-bit operation. This device is fully specified for partial-power-down applications using I off. The Ioffcircuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The CY74FCT16240T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The CY74FCT162240T has 24-mA balanced output drivers with current limiting resistors in the outputs. This reduces the need for external terminating resistors and provides for mini- mal undershoot and reduced ground bounce. The CY74FCT162240T is ideal for driving transmission lines.

Operation beyond the limits set forth may impair the useful life of the device. Unless noted, these limits are over the operating free-air temperature range. 3. Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground. 4. Typical values are at VCC =5.0V, TA= +25˚C ambient. 5. This parameter is specified but not tested. 6. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter tests, I OS tests should be performed last. 7. Tested at +25˚C.
