IDT74FCT163344/A/C 3.3V CMOS ONE-TO-FOUR ADDRESS/CLOCK DRIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS ONE-TO-FOUR ADDRESS/CLOCK DRIVER IDT74FCT163344/A/C FEATURES: - - - - - - - - - 0.5 MICRON CMOS Technology Typical tSK(o) (Output Skew) < 250ps ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) VCC = 3.3V 0.3V, Normal Range or VCC = 2.7V to 3.6V, Extended Range CMOS power levels (0.4 W typ. static) Rail-to-Rail output swing for increased noise margin Low Ground Bounce (0.3V typ.) Inputs (except I/O) can be driven by 3.3V or 5V components Available in SSOP, TSSOP and TVSOP Packages DESCRIPTION: The FCT163344/A/C is a 1:4 address/clock driver built using advanced dual metal CMOS technology. This high-speed, low power device provides the ability to fanout to memory arrays. Eight banks, each with a fanout of 4, and 3-state control provide efficient address distribution. One or more banks may be used for clock distribution. The FCT163344/A/C have series current limiting resistors. These offer low ground bounce, minimal undershoot and controlled output fall times, reducing the need for external series terminating resistors. A large number of power and ground pins ensure reduced noise levels. All inputs are designed with hysteresis for improved noise margins. The inputs of the FCT163344/A/C can be driven from either 3.3V or 5V device. This feature allows the use of these devices as translators in a mixed 3.3V/5V supply system.
