IDT72141

CMOS PARALLEL-TO-SERIAL FIFO 2048 X 9 4096 X 9 Integrated Device Technology, Inc. IDT72131 IDT72141 FEATURES: 35ns parallel port access time, 45ns cycle time 50MHz serial port shift rate Expandable in depth and width with no external components Programmable word lengths including 7-9, 16-18, 32-36 bit using Flexishift™ serial output without using any additional components Multiple status flags: Full, Almost-Full (1/8 from full), Half-Full, Almost Empty (1/8 from empty), and Empty Asynchronous and simultaneous read and write operations Dual-Port zero fall-through architecture Retransmit capability in single device mode Produced with high-performance, low power CMOS technology Available in 28-pin plastic DIP Industrial temperature range (-40oC to +85oC) is available, tested to military electrical specifications DESCRIPTION: The IDT72131/72141 are high-speed, low power parallelto-serial FIFOs. These FIFOs are ideally suited to serial communications applications, tape/disk controllers, and local area networks (LANs). The IDT72131/72141 can be configured with the IDTs serial-to-parallel FIFOs (IDT72132/72142) for bidirectional serial data buffering. The FIFO has a 9-bit parallel input port and a serial output port. Wider and deeper parallel-to-serial data buffers can be built using multiple IDT72131/72141 chips. IDTs unique Flexishift serial expansion logic (SOX, NR) makes width expansion possible with no additional components. These FIFOs will expand to a...
