1. general description the cbt3384 provides ten bits of high-speed ttl-compatible bus switching. the low on resistance of the switch allows connections to be made with minimal propagation delay. the cbt3384 device is organized as two 5-bit bus switches with two separate output enable (1 oe, 2 oe) inputs. when n oe is low, the switch is on and port a is connected to the b port. when n oe is high, each switch is disabled. the cbt3384 is characterized for operation from - 40 c to +85 c. 2. features n 5 w switch connection between two ports n ttl-compatible control input levels n multiple package options n see cbtd3384 for cbt3384 with level shifting diodes n latch-up protection exceeds 100 ma per jesd78 n esd protection: u hbm jesd22-a114e exceeds 2000 v u cdm jesd22-c101c exceeds 1000 v 3. ordering information [1] also known as qsop24 package cbt3384 10-bit bus switch with 5-bit output enables rev. 06 2 november 2009 product data sheet table 1. ordering information type number package temperature range name description version cbt3384d - 40 c to +85 c so24 plastic small outline package; 24 leads; body width 7.5 mm sot137-1 cbt3384db - 40 c to +85 c ssop24 plastic shrink small outline package; 24 leads; body width 5.3 mm sot340-1 cbt3384dk - 40 c to +85 c ssop24 [1] plastic shrink small outline package; 24 leads; body width 3.9 mm; lead pitch 0.635 mm sot556-1 cbt3384pw - 40 c to +85 c tssop24 plastic thin shrink small outline package; 24 leads; body width 4.4 mm sot355-1
