74ALVC16373 شرح
74ALVC16373
Low−Voltage 1.8/2.5/3.3 V
16−Bit Transparent Latch
With 3.6 VTolerant Inputs and Outputs
(3State, NonInverting)
The 74ALVC16373 is an advanced performance, noninverting
16bit transparent latch. It is designed for very highspeed, very
lowpower operation in 1.8 V, 2.5 V or 3.3 V systems. The
ALVC16373 is byte controlled, with each byte functioning identically,
but independently. Each byte has separate Output Enable and Latch
Enable inputs. These control pins can be tied together for full 16bit
operation.
The 74ALVC16373 contains 16 Dtype latches with 3state
3.6 Vtolerant outputs. When the Latch Enable (LEn) inputs are
HIGH, data on the Dn inputs enters the latches. In this condition, the
latches are transparent, (a latch output will change state each time its D
input changes). When LE is LOW, the latch stores the information that
was present on the D inputs a setup time preceding the
HIGHtoLOW transition of LE. The 3state outputs are controlled
by the Output Enable (OEn) inputs. When OE is LOW, the outputs are
enabled. When OE is HIGH, the standard outputs are in the high
impedance state, but this does not interfere with new data entering into
the latches.
Designed for Low Voltage Operation: VCC = 1.653.6 V
3.6V Tolerant Inputs and Outputs
High Speed Operation: 3.6 ns max for 3.0 to 3.6 V
4.5 ns max for 2.3 to 2.7 V
6.8 ns max for 1.65 to 1.95 V
Static Drive: ±24 mA Drive at 3.0 V
±12 mA Drive at 2.3 V
±4 mA Drive at 1.65 V
Supports Live Insertion and Withdrawal
IOFF Specification Guarantees High Impedance When VCC = 0 V
Near Zero Static Supply Current in All Three Logic States (40 mA)
Substantially Reduces System Power Requirements
Latchup Performance Exceeds ±250 mA @ 125°C
ESD Performance: Human Body Model >2000 V; Machine Model
>200 V
Second Source to Industry Standard 74ALVC16373
†To ensure the outputs activate in the 3state condition, the output enable pins
should be connected to VCC through a pullup resistor. The value of the resistor is
determined by the current sinking capability of the output connected to the OE pin.
