SN74LS373 : SN74LS373, SN74LS374 Octal Transparent Latch with 3−State Outputs; Octal D−Type Flip−Flop with 3−State Output The SN74LS373 consists of eight latches with 3-state outputs for bus organized system applications. The flip-flops appear transparent to the data (data changes asynchronously) when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup times is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH the bus output is in the high impedance state. The SN74LS374 is a high-speed, low-power Octal D-type Flip-Flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. A buffered Clock (CP) and O.

SN74LS373 : These 8-bit registers feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The high-impedance 3-state and increased high-logic-level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pullup components. These devices are particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight latches of the ’LS373 and ’S373 are transparent D-type latches, meaning that while the enable (C or CLK) input is high, the Q outputs follow the data (D) inputs. When C or CLK is .

SN74LS375 : 4-BIT D LATCH The SN54/ 74LS375 is a 4-Bit D-Type Latch for use as temporary storage for binary information between processing limits and input /output or indicator units. When the Enable (E) is HIGH, information present at the D input will be transferred to the Q output and, if E is HIGH, the Q output will follow the input. When E goes LOW, the information present at the D input prior to its setup time will be retained at the Q outputs.
