Probably a good chance with most equivalents to the NS ones, as they are likely to be quite similar in design (as power-consumption figures might confirm)
Although maybe the Tesla ones might be a bit different if they use different programming arrangements.
And although TI don't do an equivalent in this size, the 'half-size' SN74S287 may be rather different, with its inverted programming / bits seems to default to 1 rather than 0 when blank.
