OCTAL TRANSPARENT LATCH
WITH 3-STATE OUTPUTS;
OCTAL D-TYPE FLIP-FLOP
WITH 3-STATE OUTPUT
The SN54 / 74LS373 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
www.DataSheet4wUh.ceonmthe Output Enable (OE) is LOW. When OE is HIGH the bus output is in
the high impedance state.
The SN54 / 74LS374 is a high-speed, low-power Octal D-type Flip-Flop fea-
turing separate D-type inputs for each flip-flop and 3-state outputs for bus ori-
ented applications. A buffered Clock (CP) and Output Enable (OE) is common
to all flip-flops. The SN54 / 74LS374 is manufactured using advanced Low
Power Schottky technology and is compatible with all Motorola TTL families.
