About this item

  • LSTTL input logic compatible – VIL(max) = 0.8 V, VIH(min) = 2 V
  • CMOS input logic compatible – II ≤ 1 μA at VOL, VOH
  • Buffered inputs, 4.5 V to 5.5 V operation
  • Wide operating temperature range: -55°C to +125°C
  • Supports fanout up to 10 LSTTL loads, Significant power reduction compared to LSTTL logic ICs


The ON Semiconductor MC74HCT74AN device is identical in pinout to the LS74. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
This device consists of two D flip−flops with individual Set, Reset, and Clock inputs. Information at a D−input is transferred to the corresponding Q output on the next positive going edge of the clock input. Both Q and Q outputs are available from each flip−flop. The Set and Reset inputs are asynchronous.
