Part # 74LS75 datasheet

Part Manufacturer: Motorola


Part Description: 74LS75

Part Details:

SN54/74LS75 4-BIT D LATCH SN54/74LS77 The TTL/MSI SN54 / 74LS75 and SN54 / 74LS77 are latches used as tem- porary storage for binary information between processing units and input /out-put or indicator units. Information present at a data (D) input is transferred tothe Q output when the Enable is HIGH and the Q output will follow the datainput as long as the Enable remains HIGH. When the Enable goes LOW, theinformation (that was present at the data input at the time the transition oc-curred) is retained at the Q output until the Enable is permitted to go HIGH. 4-BIT D LATCH The SN54 / 74LS75 features complementary Q and Q output from a 4-bit LOW POWER SCHOTTKY latch and is available in the 16-pin packages. For higher component densityapplications the SN54 / 74LS77 4-bit latch is available in the 14-pin packagewith Q outputs omitted.
