FAST CMOS 16-BIT BUFFER/LINE DRIVER IDT54/74FCT16240T/AT/CT/ET IDT54/74FCT162240T/AT/CT/ET Integrated Device Technology, Inc. FEATURES: DESCRIPTION: • Common features: – 0.5 MICRON CMOS Technology – High-speed, low-power CMOS replacement for ABT functions – Typical tSK(o) (Output Skew) < 250ps – Low input and output leakage ≤1µA (max.) – ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) – Packages include 25 mil pitch SSOP, 19.6 mil pitch TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack – Extended commercial range of -40°C to +85°C – VCC = 5V ±10% • Features for FCT16240T/AT/CT/ET: – High drive outputs (-32mA IOH, 64mA IOL) – Power off disable outputs permit “live insertion” – Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V, TA = 25°C • Features for FCT162240T/AT/CT/ET: – Balanced Output Drivers: ±24mA (commercial), ±16mA (military) – Reduced system switching noise – Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V,TA = 25°C The FCT16240T/AT/CT/ET and FCT162240T/AT/CT/ET 16-bit buffer/line drivers are built using advanced dual metal CMOS technology. These high-speed, low-power devices offer bus/backplane interface capability with improved packing density. The flow-through organization of signal pins simplifies layout. The three-state controls are designed to operate these devices in a Quad-Nibble, Dual-Byte or single 16-bit word mode. All inputs are designed with hysteresis for improved noise margin. The FCT16240T/AT/CT/ET are ideally suited for driving high capacitance loads and low-impedance backplanes. The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers. The FCT162240T/AT/CT/ET have balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times– reducing the need for external series terminating resistors. The FCT162240T/AT/CT/ET are plug-in replacements for FCT16240T/AT/CT/ET and 54/74ABT16240 for on-board interface applications.
