Hello!

Looking for the following TTL series ICs:

7427, 74S27, 74LS27
7483, 74LS83
74S287 (PROM)
74S288 (PROM)
74S289
74S299, 74LS299
74LS384 (or AM25LS14?)
74LS385 (or AM25LS15)
74399, 74S399, 74LS399
74LS471 (PROM)
74S472 (PROM)
74S571 (PROM)
74S573 (PROM)
74LS669
74LS670
(any LS can be ALS, but no HC/HCT types please)
(Can be used socket pulls, except for the PROMs, which MUST be blank, or
have a blank guarantee)

Qty required varies depending on which one, but average will be 500pcs.
No "target price" bull please, just quote your price for 500pcs and
we'll go from there.

Thanks. Yours, Mark.
