SN74HC373NE4

具有三态输出的八路透明 D 型锁存器 20-PDIP -40 to 85

**description/ordering information**

These 8-bit latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The eight latches of the ’HC373 devices are transparent D-type latches. While the latch-enable LE input is high, the Q outputs follow the data D inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

**Wide Operating Voltage Range of 2 V to 6 V**

**High-Current 3-State True Outputs Can ****Drive Up To 15 LSTTL Loads**

**Low Power Consumption, 80-**µ**A Max I****CC**

**Typical t****pd ****= 13 ns**

.

*6-mA Output Drive at 5 V**

**Low Input Current of 1 **µ**A Max**

**Eight High-Current Latches in a Single ****Package**

**Full Parallel Access for Loading**
