IDT72132

CMOS SERIAL-TO-PARALLEL FIFO 2048 x 9 4096 x 9 Integrated Device Technology, Inc. IDT72132 IDT72142 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 8, 9, 16-18, and 32-36 bit using Flexshift™ serial input 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 the 28-pin plastic DIP Industrial temperature range (-40oC to +85oC) is available, tested to military electrical specifications DESCRIPTION: The IDT72132/72142 are high-speed, low-power serial-toparallel FIFOs. These FIFOs are ideally suited to serial communications applications, tape/disk controllers, and local area networks (LANs). The IDT72132/72142 can be configured with the IDTs parallel-to-serial FIFOs (IDT72131/72141) for bidirectional serial data buffering. The FIFO has a serial input port and a 9-bit parallel output port. Wider and deeper serial-to-parallel data buffers can be built using multiple IDT72132/72142 chips. IDTs unique Flexshift serial expansion logic (SIX, ) makes width expansion possible with no additional components. These FIFOs will expand ...
