IDT54FCT541 equivalent to FASTTM speed and drive IDT54/74FCT541A up to 25% faster than FAST IDT74FCT541C up to 55% faster than FAST IOL = 64mA (commercial) and 48mA (military) CMOS power levels (1mW typ. static) MIlitary product compliant to MIL-STD-883, Class B Meets or exceeds JEDEC Standard 18 specifications Available in the following packages: - Commercial: SOIC - Military: CERDIP, LCC
DESCRIPTION:
The IDT octal buffer/line drivers are built using an advanced dual metal CMOS technology. The FCT541 is designed to be employed as a memory and address driver, clock driver and bus-oriented transmitter/receiver which provides improved board density. The FCT541 is similar in function to the FCT244, except that the inputs and outputs are on opposite sides of the package. This pinout arrangement makes these devices especially useful as output ports for microprocessors and as backplane drivers, allowing ease of layout and greater board density.
