For some Computer History Museum work I need
information on 7400 series Flip
Flops (S and Normal, DIPs) circa 1973 (anything 1970-75). Anyone have any
maximum clock speed and OEM volume pricing information on parts such as 7473
thru 79 or 74106-116?
At introduction (May 1966) The 7474 (25Mhz toggle freq) was $11.40, $9.10, $7.70
quantity 1/25/100, respectively
The most expensive TI TTL part at that time was the 7491 9 bit shift register at
$31.25, $24.85, $21.25
Their most expensive IC was the linear SN354A Demodulator/Chopper at
$145, $116, $99
