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).
