Overview
PI74LPT16373 Fast CMOS 3.
3V 16-Bit Transparent Latch Features • Compatible with LCX™ and LVT™ families of products • Supports 5V Tolerant Mixed Signal Mode Operation – Input can be 3V or 5V – Output can be 3V or connected to 5V bus • Advanced Low Power CMOS Operation • Excellent output drive capability: Balanced drives (24 mA sink and source) • Pin compatible with industry standard double-density pinouts • Low ground bounce outputs • Hysteresis on all inputs • Industrial operating temperature range: –40°C to +85°C • Multiple center pins and distributed Vcc/GND pins minimize switching noise • Packaging: – 48-pin 240-mil wide thin plastic TSSOP (A) – 48-pin 300-mil wide plastic SSOP (V) Description Pericom Semiconductor’s PI74LPT16373 is a 16-bit transparent latch designed with 3-state outputs and are intended for bus oriented applications.
The Output Enable and Latch Enable controls are organized to operate as two 8-bit latches or one 16-bit latch.
When Latch Enable (LE) is HIGH, the flip-flops appear transparent to the data.
The data that meets the set-up time when LE is LOW is latched.
When OE is HIGH, the bus output is in the high impedance state.
The PI74LPT16373 can be driven from either 3.
3V or 5.
0V devices allowing this device to be used as a translator in a mixed 3.
3/5.
0V system.
