HD74HC374

HD74HC374, HD74HC534 Octal D-type Flip-Flops (with 3-state outputs) Octal D-type Flip-Flops (with inverted 3-state outputs) REJ03D0620-0200 (Previous ADE-205-499) Rev.2.00 Mar 30, 2006 Description These devices are positive edge triggered flip-flops. The difference between HD74HC374 and HD74HC534 is only that the former is a true outputs and the latter is a false outputs. Data at the D inputs, meeting the setup and hold time requirements, are transferred to the Q outputs on positive going transitions of the clock (CK) input. When a high logic level is applied to the output control (OC) input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements. Features High Speed Operation: tpd (Clock to Q) = 18 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC374P HD74HC534P DILP-20 pin PRDP0020AC-B (DP-20NEV) P HD74HC374FPEL HD74HC534FPEL SOP-20 pin (JEITA) PRSP0020DD-B (FP-20DAV) FP HD74HC534RPEL SOP-20 pin (JEDEC) PRSP0020DC-A (FP-20DBV) RP HD74HC374TELL TSSOP-20 pin PTSP0020JB-A (TTP-20DAV) T Note: Please consult the sales office for the above package availability.
