FAST CMOS 18-BIT R/W BUFFER Integrated Device Technology, Inc. IDT54/74FCT162701T/AT FEATURES: 0.5 MICRON CMOS Technology Typical tSK(o) (Output Skew) < 250ps Low input and output leakage ≤1µ A (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 Balanced Output Drivers: ±24mA (commercial), ±16mA (military) Reduced system switching noise Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, TA = 25°C Ideal for new generation x86 write-back cache solutions Suitable for modular x86 architectures Four deep write FIFO Latch in read path Synchronous FIFO reset DESCRIPTION: The FCT162701T/AT is an 18-bit Read/Write buffer with a four deep FIFO and a read-back latch. It can be used as a read/write buffer between a CPU and memory or to interface a high-speed bus and a slow peripheral. The Ato-B (write) path has a four deep FIFO for pipelined operations. The FIFO can be reset and a FIFO full condition is indicated by the full flag (FF). The B-to-A (read) path has a latch. A HIGH on LE, allows data to flow transparently from B-to-A. A LOW on LE allows the data to be latched on the falling edge of LE. The FCT162701T/AT has a balanced output drive with series termination. This provides low ground bounce, minimal undershoot and controlled output edge rates. FUNCTIONAL ...
