SN54LS604

The SN54LS604 is a type of octal 2-input multiplexed latches, which is ideal for storing data from two input buses. A and B, and providing the output bus with stored data from either the A or B register. The clock loads data in the pos otive-going transition.

Features of SN54LS604 are: (1)choice of outputs: three state; (2)16 D-type registers. one for each data input; (3)multiplex selects stored data from either A bus or B bus;(4)application oriented: maximum speed.

The recommended operating conditions and electrical characteristics of the SN54LS604 can be summarized as: (1)supply voltage: 4.5V min, 5V typ and 5.5V max; (2)high level output current: -1mA max; (3)low level output current: 12mA max; (4)width of clock pulse: 20ns min; (6)setup time: 20ns min; (7)hold time: 0ns min; (8)operating free-air temperature:-55 min and 125 max. Electrical characteristics: (1)high-level input voltage: 2V min; (2)low-level in put voltage: 0.7V max; (3)input clamp voltage(VCC=min, I1=-18mA): -1.5V max; (4)supply current(Vcc=max): 50mA typ and 70mA max; (5)short-circuit output current(VCC=max):-30mA min and -130mA max, etc.
