74LVT162374
3.3 V 16-bit edge-triggered D-type flip-flop with 30
termination resistors; 3-state
Rev. 03 — 17 January 2005
Product data sheet
1. General description
The 74LVT162374 is a high performance BiCMOS product designed for VCC operation at
3.3 V.
The 74LVT162374 is designed with 30 series resistance in both the HIGH and LOW
states of the output. This design reduces line noise in applications such as memory
address drivers, clock drivers, and bus receivers/transmitters.
This device is a 16-bit edge-triggered D-type flip-flop featuring non-inverting 3-state
outputs. The device can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the
positive transition of the clock (CP), the Q outputs of the flip-flop take on the logic levels
set up at the D inputs.
2. Features
s 16-bit edge-triggered flip-flop
s 3-state buffers
s Output capability: +12 mA and 12 mA
s TTL input and output switching levels
s Input and output interface capability to systems at 5 V supply
s Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused
inputs
s Live insertion and extraction permitted
s Outputs include series resistance of 30 making external resistors unnecessary
s Power-up reset
s Power-up 3-state
s No bus current loading when output is tied to 5 V bus
s Latch-up protection exceeds 500 mA per JESD78
s ESD protection:
x MIL STD 883 method 3015: exceeds 2000 V
x Machine model: exceeds 200 V

[1] All typical values are at VCC = 3.3 V and Tamb = 25 °C.
[2] For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.
[3] Unused pins at VCC or GND.
[4] This is the bus-hold overdrive current required to force the input to the opposite logic state.
[5] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V
a transition time of 100 µs is permitted. This parameter is valid for Tamb = 25 °C only.
[6] ICC is measured with outputs pulled to VCC or GND.
[7] This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
