INt+ A (Is tof} NC description . IN- A [6 91} Vec+ The MC1545 and MC1445 are general-purpose, out + (7 sf) Vec- gated, dual-channel wideband amplifiers designed for use in video-signal mixing and switching. Channel selection is accomplished by control of the voltage level at the gate. A high logic level selects channel A; a low logic fevel FUNCTION TABLE NCNo internal connection An . lecte 1 will lst canna 8 Th unelected hanna w careneut [aa 9 . * H Channel A oo The MC1545 is characterized for operation over L Channel B c the full military operating temperature range of S ~55C to 125C.
