You might be interested in a new part from Motorola, it's the
MC145406. It's a CMOS tranceiver that combines the functions of the
1488 and 1489. It contains 3 drivers and 3 receivers. It runs on +-5
V. And it uses 1/10 the power of the 1488. Price is $1.59 in 100-unit
quantities (see _Electronic Design_, August 8,1985, pg. 149).
